Sum-of-Squares, Counting Logics and Graph Isomorphism

Bâtiment Lavoisier, salle LAV108

Abstract: The isomorphisms between two graphs can be described by the integral solutions of a system of linear equations and inequalities. We show that the Lasserre hierarchy of increasing...[details]

Approximating planar multicut

Salle de séminaire (4B05R) - Bâtiment Copernic

Let G be a graph and R a set of pairs of vertices, called pairs of terminals. A multicut is a set of edges of G whose removal disconnects each pair in R. Computing the minimum multicut is hard both...[details]

Description :Erdos-Posa Property of Chordless Cycles and its Applications

Salle de séminaire (4B05R) - Bâtiment Copernic

Abstract: A chordless cycle is a cycle of length at least 4 that has no chord. We prove that the class of all chordless cycles has the Erdos-Posa property, which re...[details]

Easily testable properties of dense graphs

Salle de séminaire (4B05R) - Bâtiment Copernic

Abstract: A graph of size n is ɛ-far from having a property P if one have to add or delete at least ɛn² edges of G to have a graph satisfying P. A graph property P is testable if f...[details]
