2013-06-03 12:00-13:00 FAMNIT-SEMIN (Kettejeva 1, Koper) Alexander Vasilyev Introduction to Mathchem – Python package for calculating topological indices. Molecular descriptors play an important role in contemporary QSAR/QSPR research. However there is a lack of open-source and cross-platform software able to…

2013-05-27 10:00-11:00 FAMNIT-SEMIN (Kettejeva 1, Koper) Boštjan Frelih On 2-distance-balanced graphs A graph $X$ is said to be distance-balanced if for any edge $uv$ of $X$, the number of vertices closer to $u$ than to $v$ is equal to the…
2013-05-20 10:00 – 11:00 FAMNIT-SEMIN (Kettejeva 1, Koper)) Samed Bajrić On Generalized Bent Functions With Dillon’s Exponents In this talk we investigate the possibility of constructing bent functions over fields with odd characteristic. We show that the necessary and sufficient…

2013-05-06 10:00-11:00 FAMNIT-SEMIN Sergio Hiroki Koike Quintanar Flag bicolorings and pseudo-orientations of maps. The idea of consistent colorings of the flags of a map with two colors has appeared previously in the literature in di ferent contexts. This talk present…
2013-04-29 10:00-11:00 FAMNIT-SEMIN Prof. György Kiss (Eötvös Loránd University, Hungary) On m-factorizations of complete multigraphs and designs The complete multigraph $\lambda K_{v}$ has $v$ vertices and $\lambda$ edgesjoining each pair of vertices. An $m$-factor of the complete multigraph$\lambda K_{v}$ is a…
2013-04-22 10:00-11:00 FAMNIT-SEMIN Dijana Ilišević (University of Zagreb, Croatia) Generalized Bicircular Projections A projection P on a complex Banach space X is called a generalized bicircular projection if the mappingP + a( I-P ) is an isometry for some modulus one complex number a. …
2013-04-15 10:00-11:00 FAMNIT-SEMIN Arjana Žitnik (FMF, Ljubljana) TheCover Each finite graph on n vertices determines a special (n-1)-fold covering graph that we call TheCover. Several equivalent definitions and basic properties about this remarkable construction are presented. In particular, we show…
