Stability of the weak Haagerup property under graph products

In this paper, we prove that: Any graph product of finitely many groups, all of them satisfying weak Haagerup property with [Formula: see text], also satisfies weak Haagerup property and as a corollary of this result we obtain that the free product of weakly Haagerup groups with [Formula: see text], again has weak Haagerup property with [Formula: see text].
