Felix Christian Clemen, Triangles in the Plane
Room B332 IBS (기초과학연구원)A classical problem in combinatorial geometry, posed by Erdős in 1946, asks to determine the maximum number of unit segments in a set of $n$ points in the plane. Since …

Seminars and Colloquiums
Michał Pilipczuk, Monadic stability and monadic dependence
Room B332 IBS (기초과학연구원)We will give an overview of the recent attempts of building a structure theory for graphs centered around First-Order transductions: a notion of containment inspired by finite model theory. Particularly, …
Karim Adiprasito, Ehrhart theory revisited: Algebraic aspects, unimodality and more
Room B332 IBS (기초과학연구원)Ehrhart theory is the study of lattice polytopes, specifically aimed at understanding how many lattice points are inside dilates of a given lattice polytope, and the study has a wide …
Eng Keat Hng, Graphon branching processes and fractional isomorphism
Room B332 IBS (기초과학연구원)In 2005, Bollobás, Janson and Riordan introduced and extensively studied a general model of inhomogeneous random graphs parametrised by graphons. In particular, they studied the emergence of a giant component …
Yulai Ma, Pairwise disjoint perfect matchings in regular graphs
Room B332 IBS (기초과학연구원)An $r$-graph is an $r$-regular graph in which every odd set of vertices is connected to its complement by at least $r$ edges. A central question regarding $r$-graphs is determining …
