Z. Kamont et al., DIFFERENTIAL AND DIFFERENCE INEQUALITIES GENERATED BY MIXED PROBLEMS FOR HYPERBOLIC FUNCTIONAL-DIFFERENTIAL EQUATIONS WITH IMPULSES, Applied mathematics and computation, 80(2-3), 1996, pp. 127-154
The paper deals with initial-boundary value problems for impulsive fun
ctional differential equations. Theorems on impulsive functional diffe
rential and difference inequalities are obtained. Comparison results i
mplying uniqueness criteria are proved. A result on the convergence of
difference methods is given. (C) Elsevier Science Inc., 1996
