The main purpose of this paper is to present Jungck type fixed point theorems [G. Jungck
, Am. Math. Mon. 83, 261-263 (1976; Zbl 0321.54025
); the reviewer, Math. Semin. Notes, Kobe Univ. 7, 91-97 (1979; Zbl 0419.54029
)] in general probabilistic structures. Indeed, the authors obtain common fixed point theorems for symmetric spaces and then present these results in probabilistic analysis. Subsequently, several results from G. Jungck [loc. cit.], the first author [Math. Jap. 44, No. 3, 487-493 (1996; Zbl 0868.47048
)], the reviewer [loc. cit.] and elsewhere are generalized.
