A GENERAL FORM OF RETARDED INTEGRAL INEQUALITY WITH TWO VARIABLES AND ITS APPLICATION
一个推广的二变量时滞积分不等式及其应用

This paper is concerned with a general form of retarded integral inequalitywith two variables, which includes both one one-fold integral and two two-fold integrals, the latter contain two different composite functions of unknown function without assumption of monotonicity. By using the monotonization technique, anestimate for the unknown function in the integral inequality is given. The result is used to estimate the solution of an integro-differential equation.
