Positive Solutions of a Nonlinear Elliptic Equation Involving a Singular Term
In this work, we study the existence and uniqueness of positive solutions to the equation $\Delta_p\, u=f(\vert x \vert)/u(x)$, $x\in \mathbb{R}^{N}$, where $N > p > 2$. More precisely, under certain assumptions concerning the function $f$, we provide an answer to the question of globa...

Journal of Mathematical Physics, Analysis, Geometry| Резюме: | In this work, we study the existence and uniqueness of positive solutions to the equation $\Delta_p\, u=f(\vert x \vert)/u(x)$, $x\in \mathbb{R}^{N}$, where $N > p > 2$. More precisely, under certain assumptions concerning the function $f$, we provide an answer to the question of global existence formulated in [14] by using the theory of invariant manifolds in dynamical systems and the energy method. In addition, we perform a detailed analysis of the asymptotic behavior of solutions by using logarithmic transformations.
