A Numerical Solution of Fractional Optimal Control Problems Using Spectral Method and Hybrid Functions

seyed mehdy shafiof; Javad Askari; Maryam Shams Solary

Volume 3, Issue 1 , July 2018, Pages 1-25

https://doi.org/10.30473/coam.2019.46969.1119

Abstract
  In this paper‎, ‎a modern method is presented to solve a class of fractional optimal control problems (FOCPs) indirectly‎. ‎First‎, ‎the necessary optimality conditions for the FOCP are obtained in the form of two fractional differential equations (FDEs)‎. ‎Then‎, ...  Read More

Best Proximity Point Result for New Type of Contractions in Metric Spaces with a Graph

Kamal Fallahi

Volume 3, Issue 1 , July 2018, Pages 65-73

https://doi.org/10.30473/coam.2019.45808.1112

Abstract
  In this paper‎, ‎we introduce a new type of graph contraction using a special class of functions and give a best proximity point theorem for this contraction in complete metric spaces endowed with a graph under two different conditions‎. ‎We then support our main theorem by a non-trivial ...  Read More

Universal Approximator Property of the Space of Hyperbolic Tangent Functions

Mohammad Hadi Noori Skandari

Volume 3, Issue 1 , July 2018, Pages 75-85

https://doi.org/10.30473/coam.2019.45540.1111

Abstract
  In this paper, first the space of hyperbolic tangent functions is introduced and then the universal approximator property of this space is proved. In fact, by using this space, any nonlinear continuous function can be uniformly approximated with any degree of accuracy. Also, as an application, this space ...  Read More
