Abstract

In J. SJÖSTRAND, Analytic singularities and microhyperbolic boundary value problems. Math. Annalen, 254, pp. 211-256 (1980), J. Sjöstrand has developed a general theory of the propagation of analytic singularities in boundary value problems. In the present paper, we use this theory to investigate problems which give rise to a propagation in the boundary of non diffractive type. More precisely, we prove the existence of a supersonic boundary wave in the oblique derivative problem and also of the Rayleigh wave in the study of the propagation of elastic waves in an isotropic medium.
