Bifurcation in two parameters for a quasilinear Schrödinger equation Arcoya Álvarez, David Carmona, José Martínez-Teruel, Miguel Bifurcation theory Schrodinger-equation This research has been funded by Junta de Andalucía (grant FQM-116), by the Spanish Ministry of Science and Innovation, Agencia Estatal de Investigación (AEI) and Fondo Europeo de Desarrollo Regional (FEDER) (grant PID2021-122122NB-I00) and by the FPU predoctoral fellowship of the Spanish Ministry of Universities (FPU21/05578). This paper deals with existence and multiplicity of positive solutions for the quasilinear Schrödinger equation. We use bifurcation theory to analyze the set of positive solutions. 2025-11-27T12:47:39Z 2025-11-27T12:47:39Z 2025 journal article Arcoya Álvarez, D., Carmona, J. y Martínez-Teruel, M.
