【Abstract】 In this paper, the method of boundary layer corrections and the differential inequality theory are developed to study the two -parameter boundary value problems for a class of Voltcrra type of integral diffcrcngial equations. Under appropriate as-sumptions the existence of solutions is proved and the uniformly valid asymptotic expansins of the solutions arc construtcd.更多还原
