From Orientably Regular Maps to Cyclic Complementary Extensions of Finite Groups

Abstract:
Orientably regular maps are defined via the existence of a group of orientation preserving automorphisms acting regularly on the set of darts of the map. It is therefore perhaps not surprising that the study of orientably regular maps led to insights in finite permutation group theory. The concept of a skew-morphism - developed in the context of regular Cayley maps and introduced more than 20 years ago - constitutes one such example bridging topological graph theory and cyclic complementary extensions of groups. While automorphism groups of regular Cayley maps can be easily seen to be cyclic complementary extensions of their underlying groups via special structure preserving skew-morphisms, it is a bit more surprising that all skew-morphisms give rise to cyclic complementary extensions; which became known under the name of skew-products. It is even more surprising that all cyclic complementary extensions give rise to a skew-morphism. Nevertheless, not all cyclic complementary extensions are skew-products which left a gap in our understanding of cyclic complementary extensions of finite groups.
Recently, together with Kan Hu, we have been able to fill this gap by introducing a generalization of the power function of a skew-morphism which we call an extended power function, and by finding a universal construction of cyclic complementary extensions of groups via skew-morphisms and their extended power functions. We have shown that all cyclic complementary extensions are constructed in this way which means that in order to classify cyclic complementary extensions of a specific finite group it suffices to classify its skew-morphisms and their extended power functions. In view of this, we started investigating extended power functions of special classes of skew-morphisms, and completed the classification of extended power functions of group automorphisms of cyclic groups. 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. ]]> [FMFI] Prednášky a semináre [FMFI] Kalendár Martin.Macaj@fmph.uniba.sk Wed, 01 May 2024 22:26:00 +0200 https://uniba.sk/ Tuesday 7.5.2024 at 14:00, Lecture rook F2/125 Eugenia Boffo:
On the N=2 spinning particle Abstract: 
The spinning particle, which is a relativistic massless particle with a supersymmetric worldline, is the particle analogue of the Ramond-Neveu-Schwarz superstring. As such, it can serve as a playground for the understanding of second quantized string theory. Within the context of Becchi-Rouet-Stora-Tyutin cohomological techniques, different sectors arise for the representation of the bosonic ghosts associated with supersymmetry, and are distinguished by different picture numbers. After explaining some basics of differential geometry of supermanifolds, I will discuss BRST cohomology, which emerges also from the Poincare'-Hilbert series (besides just from direct computation). Such series is a very convenient means to compute the partition function and extract various kinds of information. For the case under inspection, the specific results will be highlighted.
Next I will turn to the second quantization of the spinning particle, which yields a (gauge) field theory. BRST can only reproduce the classical free BV theory, and leaves one to wonder whether it would be possible to get the interactions too. After all, homotopy Lie algebras are known to help in this regard. Moreover, in open string field theory the interactions have already been constructed thanks to the work of Witten (Phys. Rev. D 46, 5467 (1992)). In the case of a spinning particle, I will discuss the necessity of a different approach, that relies instead on the existence of a convenient deformation of the BRST operator by fields. All concepts shall be sufficiently defined and explained. ]]> [FMFI] Prednášky a semináre [FMFI] Kalendár Peter.Matak@fmph.uniba.sk Wed, 01 May 2024 22:12:00 +0200 https://uniba.sk/ Monday 6.5.2024 at 13:10, Lecture room I/9 Radovan Gregor:
Mirroring mechanisms for trustworthy human-robot interaction Abstract:
The discovery of a group of neurons in the premotor cortex of macaque monkeys that became active both when the monkeys performed certain actions and when they observed another individual performing the same actions proposed the existence of a neural system that "mirrors" the actions of others,giving rise to a name Mirror Neuron System (Rizzolatti G., 1992). This discovery has had a major impact on our understanding of the neural basis of social cognition and has been the subject of numerous studies.
This presentation will investigate the use of mirroring mechanisms for establishing trustworthy human-robot interaction. Specifically, it will focus on designing a MNS model based on neural networks, implementing it in a humanoid robot NICO and evaluating its effectiveness in human-robot interaction scenarios. ]]> [FMFI] Prednášky a semináre [FMFI] Kalendár Damas.Gruska@fmph.uniba.sk Wed, 01 May 2024 21:58:00 +0200
