    Convergence of a Two-parameter Family of Conjugate Gradient Methods with a Fixed Formula of Stepsize
    (Boletim da Sociedade Paranaense de Matemática., 2020) BOUAZIZ Khelifa; LASKRI Yamina (Co-Auteur)
    We prove the global convergence of a two-parameter family of conjugate gradient methods that use a new and different formula of stepsize from Wu [14]. Numerical results are presented to confirm the effectiveness of the proposed stepsizes by comparing with the stepsizes suggested by Sun and his colleagues [2,12].

    Existence of global solutions and blow-up results for a class of p(x)−Laplacian Heat equations with logarithmic nonlinearity
    (Published by Faculty of Sciences and Mathematics, University of Niˇs, Serbia, 2023-03-19) LALMI Abdellatif; TOUALBIA Sarra (Co-Auteur); LASKRI Yamina (Co-Auteur)
    This paper’s main objective is to examine an initial boundary value problem of a quasilin ear parabolic equation of non-standard growth and logarithmic nonlinearity by utilizing the logarithmic Sobolev inequality and potential well method. Results of global existence, estimates of polynomial decay, and blowing up of weak solutions have been obtained under certain conditions that will be stated later. Our results extend those of a recent paper that appeared in the literature

    On Stability of Second Order Pantograph Fractional Differential Equations in Weighted Banach Space
    (Fractal and Fractional, 2023) LASKRI Yamina (Co-Auteur)
    This work investigates a weighted Banach space second order pantograph fractional differential equation. The considered equation is of second order, expressed in terms of the Caputo– Hadamard fractional operator, and constructed in a general manner to accommodate many specific situations. The asymptotic stability of the main equation’s trivial solution has been given. The primary theorem was demonstrated in a unique manner by employing the Krasnoselskii’s fixed point theorem. We provide a concrete example that supports the theoretical findings.
