Existence and stability results are obtained via fixed point theorem. Examples are given to illustrate an abstract theory developed here.}, pages = {33--45}, title = {EXISTENCE AND STABILITY OF MILD SOLUTIONS OF SEMILINEAR DIFFERENTIAL EQUATIONS IN LOCALLY CONVEX SPACES}, volume = {35}, year = {1987} }
