Abstract
The purpose of this paper is to establish local theory for retarded functional differential equations with infinite delay, Some new conditions are proposed, and new results are obtained which is more general than the previous one. Our phase space is pseudo-metric space. We do not need x+ to be continuous in t on phase space. Our theorems are especially effective for Volterra integro-differential equations
