EXISTENCE AND COMPARISON RESULTS OF SOLUTIONS FOR NONLINEAR RANDOM INTEGRAL AND DIFFERENTIAL EQUATIONS RELATIVE TO WEAK TOPOLOGY

In this paper,we prove several existence theorems of random solutions to nonlinearrandom Volterra integral equations under the weak topology of Banach spaces.Then,asapplications,we obtain the existence theorems of weak random solutions to randomdiffrential equations. Existence of extremal random solutions and a random comparisontheorem for these random equations are also obtained.Our theorems imaprove and extendthe corresponding resulls in [4,5,10,11,12].
