Joonkyung Lee (이준경), On graph norms for complex-valued functions
Room B232 IBS (기초과학연구원)For any given graph $H$, one may define a natural corresponding functional $\|.\|_H$ for real-valued functions by using homomorphism density. One may also extend this to complex-valued functions, once $H$ …

Chun-Hung Liu (劉俊宏), Asymptotic dimension of minor-closed families and beyond
Zoom ID:95464969835 (356260)The asymptotic dimension of metric spaces is an important notion in geometric group theory. The metric spaces considered in this talk are the ones whose underlying spaces are the vertex-sets …

Jeong Ok Choi (최정옥), Various game-theoretic models on graphs
Room B232 IBS (기초과학연구원)We introduce some of well-known game-theoretic graph models and related problems. A contagion game model explains how an innovation diffuses over a given network structure and focuses on finding conditions …

Jaeseong Oh (오재성), A 2-isomorphism theorem for delta-matroids
Room B232 IBS (기초과학연구원)Whitney’s 2-Isomorphism Theorem characterises when two graphs have isomorphic cycle matroids. In this talk, we present an analogue of this theorem for graphs embedded in surfaces by characterising when two …

Daniel Cranston, Vertex Partitions into an Independent Set and a Forest with Each Component Small
Zoom ID: 869 4632 6610 (ibsdimag)For each integer $k\ge 2$, we determine a sharp bound on $\operatorname{mad}(G)$ such that $V(G)$ can be partitioned into sets $I$ and $F_k$, where $I$ is an independent set and $G$ …
