Fixed-Point Theorems in Complete Gauge Spaces and Applications to Second-Order Nonlinear Initial-Value Problems

الملخص EN

We establish fixed-point results for mappings and cyclic mappings satisfying a generalized contractive condition in a complete gauge space.

Our theorems generalize and extend some fixed-point results in the literature.

We apply our obtained results to the study of existence and uniqueness of solution to a second-order nonlinear initial-value problem.
