abstract:
Several linear and nonlinear integral inequalities for multi-variable functions 
developed in the literature are presented. These inequalities can be used as 
ready and powerful tools in the analysis of various classes of hyperbolic 
partial differential, integral, and integro-differential equations. In addition, 
some new nonlinear retarded integral inequalities for Gronwall-Bellman-type 
multi-variable functions of are established. Applications of some of the 
existing inequalities as well as the new ones are included.
