Christian Enss,Siegfried Hunklingerribing the location of singularities of fundamental solutions which correspond to main reflected waves, lateral waves and boundary waves. Tsuji also studied the same problem in the cases where operators are homogeneous and obtained similar results. On the other hand outer estimates of the locat

Christian Enss,Siegfried Hunklingerade composites, open and closed waveguides, periodic media and many others. A theory which treats all of these phenomena on the same footing can provide only the most superficial information about the structure of acoustic waves.

Propagation of Singularities for Hyperbolic Mixed Problems,uarter-space making use of the method of stationary phase. Deakin treated first order hyperbolic systems by the same method. However, it seems that it is difficult to apply the method to the study of fundamental solutions for more general hyperbolic mixed problems. Matsumura gave an inner es
