Positivity results for indefinite sublinear elliptic problems via a continuity argument
Uriel Kaufmann, Humberto Ramos Quoirin, Kenichiro Umezu
We establish a positivity property for a class of semilinear elliptic problems involving indefinite sublinear nonlinearities. Namely, we show that any nontrivial nonnegative soluti…

Strictly positive solutions for one-dimensional nonlinear elliptic problems
Uriel Kaufmann, Ivan Medri
We study existence and nonexistence of strictly positive solutions for the elliptic problems of the form in a bounded open interval, with zero boundary…
