In this paper, we present some new fixed point theorems for probabilistic contractions with a gauge function ϕ in generalized probabilistic metric spaces proposed by Zhou et al. Our theorems not only are generalizations of the corresponding results ofĆirić [L.Ćirić, Nonlinear Anal., 72 (2010), 2009-2018 and Jachymski [J. Jachymski, Nonlinear Anal., 73 (2010), 2199-2203, but also improve and extend the recent results given by Zhou et al.
