Random Directional Contractors and Their Applications

  • In this paper, as the generalizations of Altman's directional contractors[4,5] and Lee and Padgett's random contractors[1,2] we introduce the concept of random directional contractors for set-valued random operators. Using the new concept and transfinite induction, we show several existence theorems to solutions of nonlinear set-valued random operator equations. Our theorems improve and generalize the corresponding results in [1,2,4,5,11]. Next, some applications of our results to nonlinear random integral and differential equations are given.
