EXISTENCE OF POSITIVE SOLUTIONS OF ABSTRACT SEMILINEAR FUNCTIONAL DIFFERENTIAL EQUATIONS

本文利用算子半群理论和锥压缩不动点定理 ,在合适的条件下建立了偏序

semilinear functional differential equations.Under the suitable conditions,the positive solutions are obtained by combining the theory of semigroups and the fixed point theorem of cone compression in Banach spaces.
