Séminaire de théorie spectrale et géométrie. Année 1993-1994. Chambéry: Univ. de Savoie, Fac. des Sciences, Service de Math. Sémin. Théor. Spectrale Géom., Chambéry-Grenoble. 12, 25-28 (1994).
From the text (translated from the French): “in [J. Funct. Anal. 46, 280-350 (1982; Zbl 0497.30036)], P. D. Lax and R. S. Phillips have obtained an explicit solution of the wave equation on the real hyperbolic space of dimension $$n$$. Here, we give the solution in the case of a general hyperbolic space $$(\mathbb{K} H^n,ds)$$ where $$\mathbb{K}$$ is one of the classic fields $$\mathbb{R}$$, $$\mathbb{C}$$, $$\mathbb{H}$$ or $$Ca$$”.
