Thesis
On the complexity of counting homomorphisms under surjectivity constraints
- Abstract:
-
Given two graphs G and H, a function h that maps the vertices of G to vertices of H is a (graph) homomorphism if h preserves the edges of G, i.e., whenever two vertices u, v of G share an edge then h(u) and h(v) must share an edge in H. For different H, such homomorphisms represent different structures in G, thereby providing a framework that captures some of the most fundamental combinatorial problems studied in computer science and mathematics. One prominent example is the fact that homo...
