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…
2024-03-04 15:00 — 16:00 FAMNIT-MP1 Fabio Vlacci (University of Trieste) On a matrix representation of (hyper)complex numbers and functions We will present a recent approach on matrix representation of hypercomplex regular functions. This topic has been also considered independently by…
2024-02-27 14:00 — 15:00 FAMNIT-VP1 Joy Morris (University of Lethbridge, Canada) Detecting (Di)Graphical Regular Representations Graphical and Digraphical Regular Representations (GRRs and DRRs) are a concrete way to visualise the regular action of a group, using (di)graphs. More precisely, a…
2024-02-19 15:00 — 16:00 FAMNIT-VP1 Marko Orel (University of Primorska) Marko Orel In this talk, a graph Γ = (V, E) is a finite simple graph, which means that V is a finite set and E is a family of…
