Existence of solutions for elliptic problems involving the -Laplacian operator and a discontinuous superlinear nonlinearity

Marcos A. V. Costa, Olímpio H. Miyagaki, Marcos T. O. Pimenta

In this paper, we study a class of quasilinear elliptic problems involving the Laplacian operator and a discontinuous superlinear nonlinearity governed by the Heaviside fun…

Normalized solutions to polyharmonic equations with Hardy-type potentials and exponential critical nonlinearities

Bartosz Bieganowski, Olímpio Hiroshi Miyagaki, Jacopo Schino

Via a constrained minimization, we find a solution to the problem \begin{equation*} \begin{cases} (-Δ)^m u+\fracμ{|x|^{2m}}u + λu = ηu^3 + g(u)\\ \int_{\mathbb{R}^{2m}…

Global bifurcations of nodal solutions for coupled elliptic equations

Haoyu Li, Olímpio Hiroshi Miyagaki, Zhi-Qiang Wang

We investigate the global bifurcation structure of the radial nodal solutions to the coupled elliptic equations \begin{equation} \left\{ \begin{array}{lr} -Δu+u=u^3+βuv^2\mbox{ i…
