We study the local and semi-global solvability of a class of operators with multiple characteristics. The main point is a result on propagation of singularities. It is shown that the solvability occurs with a loss of derivatives related to the order of characteristics.

Abstract
We study the local and semi-global solvability of a class of operators with multiple characteristics. The main point is a result on propagation of singularities. It is shown that the solvability occurs with a loss of derivatives related to the order of characteristics.File in questo prodotto:
