A note on probabilistic contractor couple and solutions for a system of nonlinear equations in n a menger pn-spaces

The concept of (ϕ , δ)-type probabilistic contractor couple was introduced which simplifies and weakens the definition of probabilistic contractor couple given by Zhang Shisheng. The existence and uniqueness of the solutions for a system of nonlinear operator equations with this kind of probabilistic contractor couple in N. A. Menger PN-spaces were studied. The works improve and extend the corresponding results by M. Altman, A. C. Lee, W. J. Padgett et at. CLC number: 0177.99 Document code: A
