%0 Journal Article %T Existence and uniqueness theorems on certain difference-differential equations %A Baburao G. Pachpatte %J Electronic Journal of Differential Equations %D 2009 %I Texas State University %X In the present paper, existence and uniqueness theorems for the solutions of certain nonlinear difference-differential equations are established. The main tools employed in the analysis are based on the applications of the Leray-Schauder alternative and the well known Bihari's integral inequality. %K Existence and uniqueness %K difference-differential equations %K Leray-Schauder alternative %K Bihari's integral inequality %K Wintner type %K Osgood type %U http://ejde.math.txstate.edu/Volumes/2009/49/abstr.html
