On the asymptotically linear problem for an elliptic equation with an indefinite nonlinearity

Mónica Clapp, Cristian Morales-Encinos, Alberto Saldaña +1

We study the semilinear elliptic problem \[ -Δu = Q_Ω |u|^{p-2}u \quad \text{in } \mathbb{R}^N, \] where \( Q_Ω = χ_Ω - χ_{\mathbb{R}^N \setminus Ω} \) for a bounded smooth…

Higher regularity estimates for solutions to -Laplacian-type models

João Vitor da Silva, Makson S. Santos, Mayra Soares

In this work, we tackle the higher regularity estimates of solutions to inhomogeneous Laplacian equations at interior critical points. Our estimates provide smoothness pro…

On the existence of a positive solution to a nonlocal logistic system with nonlinear advection terms

Willian Cintra, Romildo Lima, Mayra Soares

In this paper, we study a nonlocal logistic system with nonlinear advection terms \begin{equation*} \left\{ \begin{array}{lcl} -Δu+\vecα(x)\cdot \nabla (|u|^{p-1}u)&=&\left(a-\in…

A New Approach to Inspect Weakly Coupled Logistic Systems and their Asymptotic Behavior

Haoyu Li, Liliane Maia, Mayra Soares

We consider the weakly coupled elliptic system of logistic type, \begin{equation}\label{LS} \begin{cases} -Δu &=λ_1 u- |u|^{p-2}u+ β|u|^{\frac{p}{2}-2}u |v|{^{\frac{p}{2}-1}}v\m…

Multiplicity and Bifurcation Results for a Class of Quasilinear Elliptic Problems with Quadratic Growth on the Gradient

Fiorella Rendón, Mayra Soares

We investigate the existence, non-existence, and multiplicity of solutions to the following class of quasilinear elliptic equations \begin{align*}\tag{} -\mathrm{div}(A(x)Du)…
