In the period between 17.4.2012 and 24.4.2012 there was a minicourse “Finite p-groups: the basics, generators, and automorphisms” (10 lectures) given by Prof. Gustavo A. Fernandez Alcober (University of the Basque Country, Bilbao, Spain). Program: 1. Basic theory of finite…
16.04.2012 Lecturer: Rok Požar (IMFM Ljubljana). Title: On the split structure of lifted groups Abstract: Let p: X˜ → X be a regular covering projection of connected graphs, and let CTp denote the group of covering transformations. We present an algorithm…
02.04.2012 Lecturer: dr. Martin Mačaj (Comenius University, Slovakia and UP FAMNIT). Title: Nonorientable regular maps over linear fractional groups Abstract: It is well known that for any given hyperbolic pair (k,m) there exist infinitely many regular maps of valence k…
Ob 25. obletnici Erasmusa je slovenska nacionalna agencija CMEPIUS pripravila natečaj »Erasmus in jaz«. Nagradili bodo najboljši video posnetek, fotografijo ali zgodbo z delovnim naslovom »Izkušnja z Erasmus mobilnosti kot priložnosti za osebni in strokovni razvoj študenta«. Razglasitev rezultatov in…
28.03.2012 Lecturer: dr. Gábor Gévay (University of Szeged, Hungary) Title: Geometric (nk) configurations Abstract: In the simplest case, a geometric (nk) configuration is a set of n points and n lines such that each of the points is incident with…
26.03.2012 Lecturer: dr. Marcin Anholcer (Poznan Univeristy of Economics, Poland) Title: Group irregularity strength of graphs. Abstract: We investigate the textit{group irregularity strength} ($s_mathcal{G}(G)$) of graphs, i.e. the smallest value of $s$ such that taking any Abelian group $mathcal{G}$ of…
19.03.2012 Lecturer: dr. Oliver Schaudt (Universität zu Köln, Germany). Title: The Price of Connectivity for Vertex Cover Abstract: We study a graph parameter called the Price of Connectivity for Vertex Cover (PoC). It was recently introduced by Cardinal et al.…
12.03.2012 Lecturer: dr. Istvan Kovacs Title: The isomorphism problem for rose window graphs Abstract: For an integer n ≥ 3, and a, r ∈ {1, 2, …, n − 1} with r ≠ n/2, the rose window graph Rn (a,…
05.03.2012 Lecturer: dr. Marko Orel Title: The mathematics in computed tomography (CT) Abstract: In 1979, the Nobel Prize for Medicine and Physiology was awarded jointly to Allan McLeod Cormack and Godfrey Newbold Hounsfield, the two pioneering scientistengineers primarily…
27.02.2012 Lecturer: dr. Klavdija Kutnar Title: Cayley snarks Abstract: In this talk I will discuss the well-known conjecture that there are no snarks amongst Cayley graphs. I will present an innovative approach in solving this conjecture combining the theory of…
