One of our results (namely, Theorem 2.3) may be viewed as a possible answer to the problem of existence of a fixed point for generalized type contractive mappings in M-complete Menger PM-spaces under arbitrary t-norm.
Indeed, we not only derive the result of Dutta et al. [20], Theorem 12, as a particular case of our result, but also we notice that our Theorem 2.3 may be viewed as a possible answer to the problem of existence of a fixed point for generalized type contractive mappings in M-complete Menger PM-spaces under arbitrary t-norm.
Our Theorem 2.3 is proved in an M-complete Menger PM-space under arbitrary t-norm, therefore Theorem 2.3 can be realized as a possible answer to the problem of existence of a fixed point for generalized type contractive mappings in Menger PM-spaces.
As Alan H. Simmons explains in his new scholarly edition, part of Cambridge's complete printing of Conrad's works, the novelist distinguished between writers who treat the sea as simply "a stage" and writers in whose work the sea represents "a factor in the problem of existence".
More important, a host of unemployed citizens face the grim problem of existence, and an equally great number toil with little return.
It is worth noting that the topics dealt with in this paper seem to be of an intrinsic connection with the problem of existence and uniqueness of solutions of differential and difference equations, in both determinist and stochastic cases.
In this paper we study the problem of existence of a reduced order distributed observer.
After this, different authors considered the problem of existence of a fixed point for contraction mappings in partially ordered metric spaces; see [8, 11 13] and references cited therein.
