In the present paper, we study the existence results of positive weak solution for the fractional Fisher-Kolmogoroff steady state problem. We establish a condition under which the system under consideration has a positive weak solution. Also, we cons

In the present paper, we investigate the stability results of positive weak solution for the generalized Fisher–Kolmogoroff nonlinear stationary-state problem involving weighted p-Laplacian operator −d∆P,pu = ka(x)u[ν − υu] in Ω, Bu = 0 o

In this article, we study nonlinear systems involving several p-Laplacian operators with variable coefficients. We consider the system $$ -Delta _{p_i}u_i=a_{ii}(x)|u_i|^{p_i-2}u_i -sum_{j eq i}^{n}a_{ij}(x)|u_i|^{alpha _i}|u_j|^{alpha_j}u_j+f_i(x),

We investigate in this work necessary and sufficient conditions for having the maximum principle for nonlinear system involving singular (𝑝, 𝑞)-Laplacian operators on bounded domain of Rn . Moreover, we prove the existence of positive weak solu
