Minki Kim (김민기), Complexes of graphs with bounded independence number

Room B232 IBS (기초과학연구원)

Let G be a graph on V and n a positive integer. Let In(G) be the abstract simplicial complex whose faces are the subsets of V that do not contain an independent set of size n in G. We study the collapsibility numbers of In(G) for various classes of graphs, focusing on the class of …

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 is paired with a 2-edge-colouring α to assign conjugates. We say that H is real-norming (resp. complex-norming) if ‖.‖H (resp. there is α such that …
