2024-05-13 15:00-16:00 FAMNIT-MP1 Draženka Višnjić (University of Primorska) Homomorphisms on the Coxeter-like graphs Let ${tildeGamma}_n$ be the graph with the vertex set of all symmetric matrices $S_n(F_2)$ with coefficients from binary field $F_2={0,1}$, where two matrices $A,B in S_n(F_2)$ form…
2024-05-06 15:00-16:00 FAMNIT-MP1 Endre Boros (Rutgers University, USA) Boole’s problem and a zero-one lemma We introduce Boole's problem, and the reasonably large literature related to it. We then recall an old result of Renyi (1962) that we prefer to call "a…
2024-04-29 15:00 — 16:00 FAMNIT-MP1 Aljaž Kosmač (University of Primorska) Isogeometric collocation for solving the biharmonic equation over planar multi-patch domains We present an isogeometric collocation method for solving the biharmonic equation over planar bilinearly parameterized multi-patch domains. The…
2024-04-22 15:00-16:00 FAMNIT-MP1 Tomaž Pisanski (University of Primorska, Slovenia) Geometric symmetry of graphs This work in progress explores graphs that can be drawn in the Euclidean plane exhibiting non-trivial geometric symmetry. We investigate the significance of semiregular and quasi-semiregular automorphisms…
2024-04-15 9:50-16:30 FAMNIT-VP1 Marston Conder (University of Auckland, New Zeland) Magma Mini-Course Get ready for an exhilarating opportunity this April! Professor Marston Conder from New Zealand will grace FAMNIT with his presence to deliver an insightful mini-course on MAGMA, the…
2024-04-08 15:00-16:00 FAMNIT-MP1 Andrea Munaro (University of Parma) Polynomial-time approximation schemes for induced subgraph problems on fractionally tree-independence-number-fragile graphs We investigate a relaxation of the notion of fractional treewidth-fragility, namely fractional tree-independence-number-fragility. In particular, we obtain polynomial-time approximation schemes…
2024-03-25 15:00-16:00 FAMNIT-MP1 Tea Štrekelj (University of Ljubljana) Swap operators and the quantum max cut Swap operators act on the space $(mathbb{C}^d)^{otimes{n}}$ of n qudits by exchanging tensor factors of $(mathbb{C}^d)^{otimes{n}}$. The algebra they generate (called the d-swap matrix…
2024-03-18 15:00 — 16:00 FAMNIT-MP1 Matjaž Krnc (University of Primorska, Slovenia) Toward characterizing locally common graphs A graph H is common if the number of monochromatic copies of H in a 2-edge-coloring of the complete graph is asymptotically minimized by…
2024-03-11 15:00-16:00 FAMNIT-VP1 Ademir Hujdurović Canonical double covers and their symmetries Canonical double cover BX of a graph X is the direct product of X with K_2 (the complete graph on two vertices). Automorphisms of the base graph X naturally…
