A Generalized Nonlinear Gronwall-Bellman Inequality with Maxima in Two Variables

الملخص EN

This paper deals with a generalized form of nonlinear retarded Gronwall-Bellman type integral inequality in which the maximum of the unknown function of two variables is involved.

This form includes both a nonconstant term outside the integrals and more than one distinct nonlinear integrals.

Requiring neither monotonicity nor separability of given functions, we apply a technique of monotonization to estimate the unknown function.

Our result can be used to weaken conditions for some known results.

We apply our result to a boundary value problem of a partial differential equation with maxima for uniqueness.
