Common fixed point theorems in 2 non-Archimedean Menger -space.
Compact operators defined on 2-normed and 2-probabilistic normed spaces.
Countable extension of triangular norms and their applications to the fixed point theory in probabilistic metric spaces
Coupled fixed points of mixed monotone operators on probabilistic Banach spaces
The existence of minimal and maximal fixed points for monotone operators defined on probabilistic Banach spaces is proved. We obtained sufficient conditions for the existence of coupled fixed point for mixed monotone condensing multivalued operators.
