Sn. Mishra et al., NONLINEAR HYBRID CONTRACTIONS ON MENGER AND UNIFORM-SPACES, Indian Journal of Pure and Applied Mathematics, 25(10), 1994, pp. 1039-1052
In this paper we show the existence of solutions of functional equatio
ns Tx is an element of Px, Sx = Tx is an element of Px boolean AND Qx
and x = Tx is an element of Px boolean AND Qx under certain hybrid con
traction conditions, where S, T and P, Q are single- and multi-valued
mappings on Menger spaces. Some of the results are extended to uniform
spaces.
