We show that new critical exponents appear, related to the existence or nonexistence of sign-changing solutions and due to the fully nonlinear character of the considered problem. Furthermore, we analyze the new concentration phenomena occurring as the exponents approach the critical values. }, number={1}, journal={Bruno Pini Mathematical Analysis Seminar}, author={Leoni, Fabiana}, year={2022}, month={Jan.}, pages={9–25} }
