Positivity results for indefinite sublinear elliptic problems via a continuity argument
Kaufmann, Uriel; Ramos Quoirin, Humberto; Umezu, Kenichiro (2017)We establish a positivity property for a class of semilinear elliptic problems involving indefinite sublinear nonlinearities. Namely, we show that any nontrivial nonnegative solution is positive for a class of problems the ...
