In the class of p-spaces it is shown that (a) infinite weight is not lowered by finite-to-one maps which are open except at finitely many points, (b) metrizability is inversely preserved under finiteto-one maps which are open except at finitely many points. Proizvolov [6] showed that if the domain is a p-space, then weight' is not lowered by open(More)
The purpose of the present paper is to prove a general common fixed point theorem for six mappings via weakly compatible mappings in symmetric spaces satisfying integral type implicit relations. This generalizes and improves several known results published in the literature including those of Pathak et al. (Applied Math. E-notes 7 (2007), 222-228), Popa(More)
The aim of the present paper is to prove a common fixed point theorem for six mappings via pointwise R-weakly commuting mappings in probabilistic metric spaces satisfying contractive type implicit relations. This generalizes several known results in the literature including those of Kumar and Pant (Filomat 22:2 (2008), 43-52), Kumar and Chugh (Sci. Math.(More)
