    Iterative algorithms for monotone variational inequality and fixed point problems on Hadamard manifolds

    Mann-type Tseng’s algorithm and Halpern-type Tseng’s algorithm are shown in this article. They are used to find a common solution from the set of fixed points of nonexpansive map**s and the set of solutions ...

    New Tseng’s extragradient methods for pseudomonotone variational inequality problems in Hadamard manifolds

    We propose Tseng’s extragradient methods for finding a solution of variational inequality problems associated with pseudomonotone vector fields in Hadamard manifolds. Under standard assumptions such as pseudom...

    New Ciric Type Rational Fuzzy F-Contraction for Common Fixed Points

    In this article, common fixed point theorems for a pair of fuzzy map**s satisfying a new Ciric type rational F-contraction in complete dislocated metric spaces have been established. An example has been constru...
