Common fixed point theorems in Menger probabilistic quasimetric spaces (Q1030594)

A common fixed point theorem for three mappings in a complete Menger probabilistic quasi-metric space under a continuous t-norm \(T\) satisfying the condition \[ \lim \limits_{n\rightarrow \infty}T_{i=n}^{\infty}(1-a^i(t))=1, \] where \(a\) is a mapping from \(\mathbb{R}_+\) to \((0,1)\) is proved.
