A common fixed point for operators in probabilistic normed spaces

Probabilistic Metric spaces were introduced by Karl Menger [Alsina C., Schweizer B. and Sklar A.: "On the definition of a probabilistic normed spaces", Aequationes Math. 1993; 46: 91-8]. here we consider the equicontinuity of a class of linear operators in probabilistic normed spaces and finally, a common fixed point theorem is proved. Application to quantum Mechanics is considered
