Some new observations on fixed point results in rectangular metric spaces with applications to chemical sciences

Introduction/purpose: This paper considers, generalizes and improves recent results on fixed points in rectangular metric spaces. The aim of this is to provide much simpler shorter proofs some new Methods: Some standard methods from the point theory generalized spaces are used. Results: obtained improve well-known literature. approach has proved that Picard sequence Cauchy used prove existence solutions nonlinear problems related chemical sciences. Finally, an open question given for contractile mappings Conclusions: New with application
