František Kardoš:
Strengthening a theorem of Meyniel Abstract:
For an integer k>=1 and a graph G, let K_k(G) be the graph that has vertex set all proper k-colorings of G, and an edge between two vertices x and y whenever the coloring y can be obtained from x by a single Kempe change. A theorem of Meyniel from 1978 states that K_5(G) is connected, with diameter O(5^|V(G)|), for every planar graph G. We significantly strengthen this result, by showing that there is a positive constant c such that K_5(G) has diameter O(|V(G)|^c) for every planar graph G. This is a joint work with Quentin Deschamps, Carl Feghali, Clément Legrand-Duchesne, and Théo Pierron. More information

EU COMMISSIONER REYNDERS AT THE LAW FACULTY OF COMENIUS UNIVERSITY IN BRATISLAVA

Thu, 05 May 2022 21:21:00 +0200

On 28 April 2022, a discussion with EU Commissioner Didier Reynders, Commissioner for Justice, was held in the Auditorium Maximum room of Comenius University in Bratislava, Faculty of Law (hereinafter referred to as the “Faculty of Law”). In his position, he is responsible for ensuring the rule of law within the EU; for improving the enforcement of judgments of the Court of Justice of the EU in the event of a breach of the rule of law; for improving judicial cooperation and the exchange of information between the competent authorities in the field of justice; for maximizing the potential of the use of new digital technologies in the judiciary; for consumer protection and the protection of their rights; for ensuring full implementation and performance of GDPR, etc. The discussion was co-organized with the Representation of the European Commission in Slovakia. The discussion was attended by Dean of the Faculty of Social and Economic Sciences, Assoc. Prof. Lucia Mokrá, Dean of the Faculty of Law, Assoc. Prof. Eduard Burda, employees of the Faculty of Law, as well as bachelor's, master's and doctoral students at Comenius University in Bratislava, Faculty of Law, and Faculty of Social and Economic Sciences . The discussion was opened by the head of the Representation of the European Commission in Slovakia, Prof. Šucha, who welcomed all those present and introduced by Mr. Reynders and gave the floor to the Vice-Dean of the Faculty of Law, Comenius University in Bratislava, Dr. Andrea Szakács. She welcomed those present on behalf of the Faculty of Law and then gave the floor to Mr. Reynders. At the beginning of the discussion, Mr. Reynders informed about the war in Ukraine, the state of the rule of law in Slovakia, etc. Later, Mr. Reynders responded to questions from the auditorium that fell within his responsibilities. They concerned, e.g., misleading information, so-called hoaxes, and hate speech on social networks and instruments adopted by the EU to address these negative facts; issues of national identity protection and whether it has the potential to jeopardize further EU integration; political situation in Hungary and Poland, as Eurosceptics; possible follow-up infringement proceedings under Article 260 of the Treaty on the Functioning of the EU, unanimous versus majority voting as obstacles to the rule of law, etc. The discussion was very fruitful with well-founded and inspiring questions. We believe that this was not the last visit by the Commissioner, and we look forward to his meeting again.

Dr. André Sopczak (IEAP CTU in Prague, Czech Republic):
Higgs Boson Coupling to Top Quarks and Self-coupling Measurements Abstract:
Ten years after the discovery of the Higgs boson, precision measurements of the properties of the Higgs boson are at the forefront of research. Fundamental predictions of the Higgs theory are the strong coupling to top quarks and the Higgs boson self-coupling. In this presentation, experimental results and sensitivity expectations are discussed. Furthermore, an outlook is given to related searches for New Physics. More information

Nuclear Seminar - Natália Džalaiová (4.5.2022)

Mgr. Natália Džalaiová:
Strangeness production in Xe–Xe collisions at √sNN = 5.44 TeV with the ALICE experiment at the LHC
Abstract:
One of the leading areas of high-energy physics studies is the study of a strongly interacting matter, quark-gluon plasma (QGP). Strangeness enhancement is originally proposed as a signature of such a state. In this work, the production of multi–strange (Ξ− and Ω− ) baryons and their anti-particles measured by ALICE at LHC in Xe–Xe collisions at √sNN = 5.44 TeV is investigated. The pT spectra obtained at mid-rapidity have been studied in interval 0.6 < pT < 5 GeV/c and 1 < pT < 5 GeV/c, respectively, with centrality varying from the most central to the most peripheral collisions (up to 90%). Comparison of obtained data with pp, p–Pb and Pb–Pb systems would help to investigate the microscopic origin of enhanced strangeness production, which is not known yet.

We will show which mathematical objects can be used in Sage and also we will explain how to work with graphs and groups in Sage. Thanks to (temporary?) loosening of restrictions regarding the COVID epidemy, we intend to conduct the seminar meetings this semester `in-person'. Hence, all of you who might choose to attend in person are welcome. Those of you who are not able to attend in person or who are still uncertain about the safety of attending in person are welcome to attend via MS Teams. In either case, we hope to see as many of you as possible (either in person or virtually) at our Friday gatherings.

TEDxUniverzitaKomenskéhoLive

pr@uniba.sk — Fri, 29 Apr 2022 09:12:00 +0200

These days, recovery is mentioned often. We recover the landscape, our customs, relationships. We also often mention ‘crisis’ in the same sentence. We used to refer to the coronavirus, but now it’s the war in Ukraine, the climate or energy. When should we attempt to recover the old and when is it better to make a radical change and rebuild from the ground up? Are we going to use this recovery to modify the toxic habits of humanity? Is the "new normal" going to be more sustainable than the one before 2020? Speakers at TEDxUniverzitaKomenskéhoLive will ask these questions. Juraj Tekel is a physicist from Comenius University and will speak about why renewable sources of energy are introduced so slowly. We have been hearing about them for years, but we still burn gas to heat our homes, put petrol in our cars and generate most of our electricity from non-renewable sources. What's the deal? Lucia Mokrá, who is the Dean of the Faculty of Social and Economic Sciences, argues that truth is always revealed with time. She speaks about her way of setting up processes at the faculty, about the challenges and obstacles. She says that time will reveal the truth about universities, the quality of higher education, student brain-drain and the importance of social sciences. Will elves save social networks? Content on social networks is spiralling out of control. Now, however, trolls are taken on by elves - the moderators. Gabriel Tóth from the digital agency ‘Katedra Komunikácie’ (”Department of Communication”) studied political science at Comenius University and in his talk he will try to explore whether it is possible to win this fight. Paranoid beliefs are relatively common in the general population and may not just be a manifestation of serious mental disorders. These beliefs have a significant impact on our day-to-day relationships. Psychologist and psychiatrist Michal Hajdúk from Comenius University talks about their root causes. Co-founder of KC Dunaj, creator of the concept of the Shenk family craft brewery and of ‘Výčap u Ernőho’ (“Ernő’s Bar”) and, most recently, creator of the new multi-purpose culture and entertainment centre UniK Mlyny Ivan Pätoprstý has ample experience with recovery and restoration. Is it better to demolish and rebuild or restore and renovate? In his talk he explains why he tends to lean toward restoration. Fragile and ardent, turning into wild and rough, with a dark premonition. Katarína Máliková is a composer, producer, musician and singer. Her style combines neo-classical, minimal synth-pop with elements of experimental music, glamrock, and 70's and 80's retro music. Her contribution at the event is musical. TEDxUniverzitaKomenskéhoLive participants will have a unique opportunity to watch talks recorded during TED2022, which took place between 11 and 13 April, 2022. The speakers include Bill Gates, Adam Mosseri, Catherine Price a Garry Kasparov. "Two years of a downsized social life have shown how much we all need to share ideas live. We could not attend lectures, events, conferences. TED and TEDx events are meetings of people who are ready to share interesting ideas. I’m pleased that we managed renew the tradition after the pandemic and that we are bringing the third year of this event to our university," said Radomír Masaryk, TEDxUniverzitaKomenského Team Leader and Comenius University Vice-Rector for External Relations. "The videos of TED and TEDx talks are a popular supplementary content at university lectures and seminars because they have the potential to provoke and stimulate critical thinking. The events themselves foster an atmosphere of curiosity, exchange of ideas and of intellectual stimulation. They form experiences which the participants remember for a long time. And I believe that this is the essence of a modern university: we should be a source of such intellectual experiences," adds Marek Števček, Rector of Comenius University, who was one of the speakers at the 2019 TEDxUniverzitaKomenského with a talk entitled "Everything you need to know about the Civil Code but you did not even think to ask“. *** TEDxUniverzitaKomenského was made possible by the students of the Faculty of Social and Economic Sciences of Comenius University. They organized the first event in 2018. In 2019, they followed up on the success of the project and created an unforgettable event filled with inspiring talks. This year, the organization of the event was taken over by the External Relations Office of the Rectorate, which decided to give the event a new lease of life after the pandemic.
