Leray-volevich conditions for systems of evolution equations basing on the generalized derivative in the sense of gelfond-leontjev

摘要

Systems of evolution equations basing on the generalized derivative in the sense of Gelfond-Leontjev are considered. Using scale type estimates the sufficiency and necessity of Leray-Volevich conditions is discussed. The obtained estimates are weaker than in the special case basing on the classical complex derivative.
