报告题目：Universality of Intervals of Line Graph Partial Order

报告简介：In this talk I will speak about one of my old results about homomorphism. We prove that for every d≥3 the homomorphism order of the class of line graphs of finite graphs with maximal degree d is universal. This means that every finite or countably infinite partially ordered set may be represented by line graphs of graphs with maximal degree d ordered by the existence of a homomorphism
