STAMPACCHIA-CALDERON-ZYGMUND THEORY FOR LINEAR ELLIPTIC EQUATIONS WITH DISCONTINUOUS COEFFICIENTS AND SINGULAR DRIFT

摘要

In this paper, the existence and properties of solutions of the boundary value problem (1.4) are studied. No regularity assumptions on the coefficients of the matrix M(x) are used (in particular we do not require that the principal part is -Delta), no assumptions on the size of ||E||(LN) are needed.
