Incompatibility of quantum devices
Abstract:
One of the first things we learn about quantum systems is the Heisenberg uncertainty relation. Limitations to measure statistics of non-commutative observables are considered to be one of the key features of quantum physics. In this talk we will introduce the operational paradigm of incompatible devices - the qualitative mathematical origin of the existence of all forms of uncertainties. We will discuss "no-go" implications not only for measurement devices. Further we will formulate this concept for hypothetical general probabilistic theories that exhibit even stronger differences from classical physics, for example regarding the violation of Einstein-Podolski-Rosen idea of local realism. ]]> [FMFI] Prednášky a semináre [FMFI] Kalendár Peter.Matak@fmph.uniba.sk Thu, 12 Dec 2024 09:02:00 +0100 [Translate to English:] Seminár z teoretickej informatiky - Viliam Geffert (13.12.2024) https://uniba.sk/ [Translate to English:] v piatok 13.12.2024 o 11:00 hod. v miestnosti M 213 Prednášajúci: Viliam Geffert (UPJŠ Košice) Názov: Konverzie medzi binárnymi a unárnymi konečnostavovými automatmi Termín: 13.12.2024, 11:00 hod., M 213
Abstrakt: 
Ak L je jazyk nad binárnou abecedou {0,1}, tak jeho unárne kódovanou verziou L'= num(L) je jazyk nad unárnou abecedou {a} taký, že a^x patrí do L' vtedy a len vtedy ak nejaká binárna reprezentácia x patrí do L. (Pretože pridávaním núl na začiatok binárneho reťazca sa hodnota reprezentovaného čísla nemení, takých binárnych reprezentácii môže byť viac.) Opačne, binárne kódovanou verziou unárneho L’ je jazyk L= bin(L'), taký že num(L)= L'. Bude prezentovaná procedúra pre konverziu konečnostavového automatu rozpoznávajúceho unárny jazyk L’ na automat pre L= bin(L'), ako aj procedúra pre konverziu v opačnom smere. Konverzia v opačnom smere nie je vždy garantovaná, keďže existujú také binárne regulárne jazyky, pre ktoré ich unárne kódované verzie nie sú dokonca ani bezkontextové. (V takom prípade sa procedúra zastaví s hlásením že konečnostavový automat pre jazyk L’=num(L) neexistuje, keďže L' nie je regulárny.) Rozdiel v počte stavov v automate pre binárny jazyk L a v automate pre jeho unárne kódovanú verziu L’ môže byť až exponenciálny. ]]> [FMFI] Prednášky a semináre [FMFI] Kalendár Rastislav.Kralovic@fmph.uniba.sk Tue, 10 Dec 2024 22:30:00 +0100 The ENLIGHT Alliance evaluated the year 2024 and outlined future challenges https://uniba.sk/ On 5 December 2024, the annual meeting of Comenius University representatives in the ENLIGHT... Innovation, sustainability, and mobility are priorities The event also included lectures on innovation in teaching. Daniel Klimovský and Martina Benzoni Baláž from the Faculty of Arts spoke about their course ‘Public Policy in Slovakia’, which won the ENLIGHT Teaching & Learning Award this year. The course is based on the Challenge-Based Education concept presented by Lucia Hlavatá from the Faculty of Education. Milan Remiš and Oliver Vavro from the Erasmus+ Office of the CU Rectorate informed about increasing mobility of students and staff of Comenius University to the alliance universities. As Jozef Tancer pointed out, the upcoming challenge for the alliance will be to increase the number of mobility opportunities. Peter Hanajík from the Faculty of Natural Sciences spoke on green sustainability, presenting examples of good practice across all faculties of the university. External cooperation The Regional Academy is a platform of the ENLIGHT alliance to enable external cooperation of universities. Kateryna Yakovenko from the ENLIGHT Office of CU’s Rectorate presented the activities of the office in the past year, emphasizing the role that Comenius University plays in the development of external partnerships in the alliance. Eleven ENLIGHT activities of the Regional Academy took place since January 2024, e.g. a lecture by the Office of the Public Ombudsman at the University of the Third Age or the 'Cities in Motion’ meeting with partners from the municipal authorities of Galway, Ghent and Uppsala. External cooperation will receive a significant boost through a pilot micro-certificate project. CU currently prepares them with the ‘Clown Doctors’ civic association also for partners from Uppsala, Groningen and Göttingen.   Students as an active component of the alliance Student representatives of CU Adrián Binka and Šimon Gabčo presented the activities of the Student Network in the ENLIGHT alliance. They emphasized the importance of international cooperation, experience sharing, and showed how to become actively involved in the decision-making of the alliance.   Future challenges The meeting was concluded by vice-rector Jozef Tancer who expressed his satisfaction with the work of individual teams within the alliance and encouraged further development of cooperation. "The ENLIGHT alliance gives us unique opportunities to improve internationalization, and also to increase the quality of our education and research. In the coming years though, we need to set out on the difficult road of developing long-term sustainability of the alliance," he said.

Orientably-regular embeddings of multigraphs Abstract:
Informally, a graph embedding on some orientable surface gives an orientably-regular map if the embedding exhibits the `highest level of orientation-preserving symmetry'. Inspection of Conder's list of orientably-regular maps up to genus 300 reveals that nearly 90 per cent of them are such that either the map or its dual has a non-simple underlying graph, generating thus legitimate interest in orientably-regular embeddings of multigraphs. In the talk we will explain an approach to this topic based on group presentations and apply it to classification of regular embeddings of complete multigraphs.  More information]]> [FMFI] Prednášky a semináre [FMFI] Kalendár Martin.Skoviera@fmph.uniba.sk Tue, 10 Dec 2024 13:55:00 +0100 [Translate to English:] Úspech nášho absolventa na súťaži TAX ADVISERS AWARD https://uniba.sk/ [Translate to English:] Dňa 9 decembra 2024, Právnická fakulta Univerzity Komenského TAX ADVISERS AWARD, ktorú organizuje Slovenská komora daňových poradcov.

Proposing an Evaluation Method for Abduction Algorithms
Abstract:
Abduction is a type of inference that aims to find a hypothetical explanation for a given observation based on background knowledge. Unlike deduction and induction, abduction is not yet fully explored and is interesting to investigate mainly in the ontologies and description logics area. It has been applied, for example, in medical diagnosis, criminology and model-based diagnosis. Having researched several algorithms that can be used for any description logic regardless of its expressivity, we plan to compare them using our experimental abduction solver. However, there is no benchmark dataset for the abduction problem. Therefore, we propose a method for generating inputs using justifications.  More information ]]> [FMFI] Prednášky a semináre [FMFI] Kalendár Damas.Gruska@fmph.uniba.sk Sat, 07 Dec 2024 16:14:00 +0100 Comenius University was present at the Saco Student Fairs in Stockholm https://uniba.sk/ Bratislava, 5 December 2024: On 27 and 28 November, 2024, Comenius University Bratislava (CU) took...

Compact bound state of scalar particles
Abstract:
We study the feebly interacting dark matter with the Standard Model fields, where the preceding and the latter ones are the constituents of the bosonic cosmological objects, the scalar boson stars (BS). The scalar dark matter (SDM) massive fields can form the compact scalar bound state when minimally coupled to gravity. We consider an effective description of a more complete model with the (thermo)dynamic potential of the BS at finite temperature. The formation of the BS intuitively is explained in terms of the string-like structure of the electric fluxes of the hidden vector field under the impact (the girth) of the SDM fields. The spin 1/2 dark matter particles correspond to the flux-tube excitation with terminals. The SDM fields may fluctuate with the temperature and are established around the equilibrium state at some weak background scale. The BS may have approximately a stationary form with an asymptotically flat geometry, and the maximal mass of the star is larger than the solar mass. In the talk, the data of the LHC at CERN collected in 2016-2024, were used.]]> [FMFI] Prednášky a semináre [FMFI] Kalendár Jaroslav.Stanicek@fmph.uniba.sk Thu, 05 Dec 2024 12:16:00 +0100
