Abstract

For given graphs \( G \) and \( H \), the \({Ramsey\; number}\) \( R(G, H) \) is the least natural number \( n \) such that for every graph \( F \) of order \( n \) the following condition holds: either \( F \) contains \( G \) or the complement of \( F \) contains \( H \). In this paper, we determine the Ramsey number for a disjoint union of paths versus the cocktail party graph.

Keywords: Ramsey number, path, cocktail party graph.
