In the paper, the topological degree for a compact continuous operator defined on an open subset of a Menger PN-space is generalized. The new concept of fixed-point index in Menger PN-spaces is introduced, the most important properties of the fixed-point index are established, and some other results are given.
Keywords: fixed-point index, Menger PN-space, compact continuity, probabilistic metric space, distribution function.
