## Abstract In this article, we study the tripartite Ramsey numbers of paths. We show that in any two‐coloring of the edges of the complete tripartite graph __K__(__n__, __n__, __n__) there is a monochromatic path of length (1 − __o__(1))2__n__. Since __R__(__P__~2__n__+1~,__P__~2__n__+1~)=3__n__,
Let br k (C 4 ; K n,n ) be the smallest N such that if all edges of K N,N are colored by k +1 colors, then there is a monochromatic C 4 in one of the first k colors or a monochromatic K n,n in the last color. It is shown that br k (C 4 ; K n,n ) = (n 2 / log 2 n) for k ≥ 3, and br 2 (C 4 ; K n,n ) ≥
