    Existence and uniqueness of positive solutions for first-order nonlinear Liouville-Caputo fractional differential equations
    (University Of Eloued جامعة الوادي, 2020-02-23) Haoues Moussa; Ardjouni Abdelouaheb
    We study the existence and uniqueness of positive solutions of the rst-order nonlinear Liouville Caputo fractional differential equation ........................................................ ........................................................ where ....... In the process we convert the given fractional differential equation into an equivalent integral equation. Then we construct appropriate mappings and employ the Krasnoselskii xed point theorem and the method of upper and lower solutions to show the existence of a positive solution of this equation. We also use the Banach xed point theorem to show the existence of a unique positive solution.
