A note on critical problems involving the -Grushin Operator: existence of infinitely many solutions
Paolo Malanchini, Giovanni Molica Bisci, Simone Secchi
We consider a critical problem in a bounded domain involving the -Grushin operator . After a truncation argument, we obtain infinitely many solutions to our problem via K…
Regularizing effect of the interplay between coefficients in linear and semilinear -elliptic equations
Paolo Malanchini, Giovanni Molica Bisci, Simone Secchi
We study the regularizing effect arising from the interaction between the coefficient \(a\) of the zero order term and the datum \(f\) in the problem $$ \left\lbrace \begin{array}{…
Regularizing effect of the natural growth term in quasilinear problems with sign-changing nonlinearities
José Carmona Tapia, Paolo Malanchini, Antonio J. Martínez Aparicio +1
We investigate the existence and nonexistence of solutions to the Dirichlet problem \begin{equation*} \tag{} \label{pba} \left\{ \begin{alignedat}{2} -Δ_p u + g(u) |\nabla u|^p…
Existence and decay for a Grushin problem in with singular, convective, critical reaction
Laura Baldelli, Paolo Malanchini, Simone Secchi
We establish an existence result for a problem set in the whole Euclidean space involving the Grushin operator and featuring a critical term perturbed by a singular, convective rea…
