Abstract: The evaluation of conjunctive regular path queries - which form the navigational core of the query languages for graph databases - raises challenges in the context of the homomorphism ...

Graph homomorphisms and chromatic numbers are foundational concepts in modern graph theory, with widespread applications that extend from combinatorial optimisation to theoretical computer science. A ...

Abstract: In this work, we study the problem of linear index coding from graph homomorphism point of view. We show that the decision version of linear (scalar or vector) index coding problem is ...
