%0 Journal Article %T Existence of solutions for an abstract second-order differential equation with nonlocal conditions %A Eduardo Hernandez M. %J Electronic Journal of Differential Equations %D 2009 %I Texas State University %X We discuss the existence of mild solutions for abstract second-order differential equation with nonlocal conditions. Also we consider some application of our results. %K Second order differential equations %K cosine function of operators %K abstract Cauchy problem %U http://ejde.math.txstate.edu/Volumes/2009/96/abstr.html
