A GENERAL FORM OF RETARDED INTEGRAL INEQUALITY WITH TWO VARIABLES AND ITS APPLICATION

This paper is concerned with a general form of retarded integral inequality with 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,an estimate for the unknown function in the integral inequality is given.The result is used to estimate the solution of an integrodifferential equation.
