the main purpose of this paper is to obtain sufficient conditions for existence of points of coincidence and common fixed points for three self mappings in $b$-metric spaces. next, we obtain cone $b$-metric version of these results by using a scalarization function. our results extend and generalize several well known comparable results in the existing literature.

Schultz and Yarus (1996) propose that codon reassignment takes place through ambiguously translating intermediates, meaning ‘‘the supposition that codons are read ambiguously by two tRNAs (a tRNA and an RF [release factor] in the case of terminations), specifying insertion of more than one amino acid (or an amino acid as well as stop).’’ In simple terms, they propose that a codon can have two m...

in this paper, we study sufficient conditions for existence and uniqueness of solutions of three point boundary vale problem for p-laplacian fractional order differential equations. we use schauder's fixed point theorem for existence of solutions and concavity of the operator for uniqueness of solution. we include some examples to show the applicability of our results.

the purpose of this paper is to obtain necessary and suffcient conditionsfor existence approximate fi xed point on geraghty-contraction. in this paper,de nitions of approximate -pair fi xed point for two maps tα , sα and theirdiameters are given in a metric space.
