Autor: Michele Martins Lopes, Francielle Santo Pedro, José Paulo Carvalho dos Santos, Daniel Sánchez Ibá´ñez, Estevão Esmi, Laécio Carvalho de Barros

Publikováno v: CQD Revista Eletrônica Paulista de Matemática, Vol 22, Iss 2 (2022)

The memory effect is an interesting tool that can be seen in fractional differential equations. To show this clearly, in this paper we prove that the Caputo derivative of a function 𝑓, as well as the Riemann-Liouville integral and derivative, are

Numerical Solution for Fuzzy Initial Value Problems via Interactive Arithmetic: Application to Chemical Reactions

Autor: Vinícius F. Wasques, Estevão Esmi, Laécio C. Barros, Peter Sussner

Publikováno v: International Journal of Computational Intelligence Systems, Vol 13, Iss 1 (2020)

This paper studies numerical solutions for fuzzy initial value problems, where the initial conditions are given by interactive fuzzy numbers. The fuzzy solution is given by a numerical method that employs the arithmetic of interactive fuzzy numbers a

Adapted Fuzzy Integral: An Application in the Finite Element Method

Autor: Daniel Sánchez, Luana T. Bassani, Laécio C. Barros, Estevão Esmi

Publikováno v: Trends in Computational and Applied Mathematics, Vol 19, Iss 1 (2018)

In this paper we study and define an adapted fuzzy integral, based on the Sugeno integral. Moreover, we present a numerical integration formula which approximates the value of the adapted fuzzy integral. Thus, we prove that the Riemann integral and t
