Abstract

Various necessary minimum conditions in quasidifferential calculus are compared. These conditions as well as regularity conditions and some estimates of directional derivatives are studied concerning their dependence on the special choice of a quasidifferential. Moreover, a generalized notion of quasidifferentiability for functions possibly having infinite directional derivatives is introduced.
