Prescribing Gevrey singularities for solutions of pseudodifferential operators. (English) Zbl 1196.35238

The authors obtain conditions by means of a priori estimates to ensure the existence of distribution or smooth solutions with prescribed Gevrey wave front sets for pseudodifferential operators of finite order. To illustrate the results, a concrete example is analysed in detail.
