2019-06-10 10:00–11:00 FAMNIT-MP5 Andrés David Santamaría-Galvis (University of Primorska) Shellings from relative shellings, with application to NP-completeness A simplicial complex is shellable if it exhibits a well-behaved ordering of its maximal faces (a shelling) constructed in some precise way.Shellings have been proven useful, but they…

2019-06-05 10:00–11:00 FAMNIT-MP2 Robin Wilson (Open University, United Kingdom) Stamping through Mathematics In this talk I cover the entire history of mathematics in one hour, from earliest times to the modern age, illustrating the narrative with about 300 attractive (and…

2019-06-03 10:00–11:00 FAMNIT-MP1 Žiga Velkavrh (University of Primorska) Reputation and (Dis)honesty: A game-theoretic approach In the first part of this talk we introduce Game Theory, its solution concepts and applications. We then discuss the limits of classical game-theoretic predictions and…

2019-05-27 10:00–11:00 FAMNIT-MP1 Tibor Illés (Budapest University of Technology and Economics, Institute of Mathematics, Hungary) Sufficient linear complementarity problems: matrix classes, algorithms and applications Linear complementarity problems (LCP) generalizes some fundamental problems of mathematical optimization like linear programming (LP) problem,…

2019-05-20 10:00–11:00 FAMNIT-MP1 Daniel Hawtin (University of Rijeka, Croatia) Binary Completely Transitive Codes Given a code in a graph, the vertex set of the graph may be partitioned by the sets of vertices at each of the possible distances to…

2019-05-13 10:00–11:00 FAMNIT-MP1 Nina Chiarelli (FAMNIT and IAM, UP) Linear separation of connected dominating sets in graphs A connected dominating set in a graph is a dominating set of vertices that induces a connected subgraph. In this talk we present…

2019-05-16 11:00–12:00 FAMNIT-VP2 Elvis Baraković (University of Tuzla, Bosnia and Herzegovina) Axial torsion waves in metric-affine gravity We construct new explicit vacuum solutions of quadratic metric-affine gravity. The approach of metric-affine gravity in using an independent affine connection produces a…

2019-05-06 10:00–11:00 FAMNIT-MP1 Martin Milanič (IAM and FAMNIT, University of Primorska) Decomposing 1-Sperner hypergraphs, with applications to graphs Hypergraphs are generalizations of graphs in which edges (in this context referred to as hyperedges) can have arbitrary cardinality. A hypergraph is…

2019-04-26 11:00–12:00 FAMNIT-MP6 Riste Škrekovski (UL FMF, UP FAMNIT, IMFM, FIŠ) Some results and problems on unique-maximum colorings of plane graphs A unique-maximum coloring of a plane graph G is a proper vertex coloring by natural numbers such that each…
