%0 Journal Article %T Solutions to fourth-order random differential equations with periodic boundary conditions %A Xiaoling Han %A Xuan Ma %A Guowei Dai %J Electronic Journal of Differential Equations %D 2012 %I Texas State University %X Existence of solutions and of extremal random solutions are proved for periodic boundary-value problems of fourth-order ordinary random differential equations. Our investigation is done in the space of continuous real-valued functions defined on closed and bounded intervals. Also we study the applications of the random version of a nonlinear alternative of Leray-Schauder type and an algebraic random fixed point theorem by Dhage. %K Random differential equation %K periodic boundary conditions %K random solution %K extremal solutions %U http://ejde.math.txstate.edu/Volumes/2012/235/abstr.html
