2017-12-18 10:00-11:00 FAMNIT-POŠTA Russ Woodroofe (UP FAMNIT) Recognizing a solvable group from its subgroup lattice The subgroup lattice of a group G is the poset consisting of the subgroups of G, ordered by inclusion.  Can you recognize whether a group…

2017-12-14 11:00-12:00 FAMNIT-POŠTA Pavel Klavik (Charles University, Prague, Czech Republic) Jordan-like Characterizations of Automorphism Groups of Geometrically Represented Graphs Frucht (1939) proved that every abstract finite group is isomorphic to the automorphism group of some finite graph. Jordan (1869) studied…

2017-12-11 10:00-11:00 FAMNIT-POŠTA Karin Cvetko Vah (University of Ljubljana) Noncommutative lattices Lattices appear throughout mathematics: from logics and set theory, to algebra (congruence lattice and lattice of subvarieties), discrete mathematics (face lattice of a polytope and matroids) and topology. Noncommutative…

2017-12-04 10:00-11:00 FAMNIT-POŠTA Marko Orel (UP FAMNIT & UP IAM) The finite Minkowski space and the existence of ovoids in the orthogonal polar space Let F_q be a finite field with q elements, where q is odd, and let A=A^{top}in…

2017-11-20 10:00-11:00 FAMNIT-POŠTA Rok Požar (UP FAMNIT) Graph-theoretical approach for analysing brain activity The electrical activity generated by nerve cells of the brain can be measured through electrodes attached to various locations on the scalp.  This technique is known as…

2017-11-13 10:00-11:00 FAMNIT-POŠTA Nino Bašić (UP IAM & UP FAMNIT) Pentagonal Clusters in Fullerenes Properties of fullerenes are critically dependent on the distribution of their 12 pentagonal faces. It is well known that there are infinitely many IPR-fullerenes. IPR-fullerenes can…

2017-11-24 11:00-12:00 FAMNIT-MP1 Marko Tadić (University of Zagreb, Croatia) On non-commutative harmonic analysis and theory of automorphic forms We shall recall of basic principles of the non-commutative harmonic analysis, discuss the case of classical groups, and how problems of non-commutative…

2017-11-06 10:00-11:00 FAMNIT-POŠTA Robert Jajcay (UP FAMNIT and Comenius University (Slovakia)) Highly symmetric graphs In our talk, a highly symmetric graph will mean a vertex-transitive graph whose automorphism group is much larger than the order of the graph. We will…

2017-11-27 10:00-11:00 FAMNIT-POŠTA Vicente Munoz Velázquez (Universidad Complutense de Madrid, Spain) Complex, symplectic and Kahler geometry Kahler manifolds appear naturally in both Algebraic and Differential Geometry: projective complex varieties from Algebraic Geometry, and smooth manifolds with riemannian metrics with holonomy…
