Existence of strictly positive solutions for sublinear elliptic problems in bounded domains
Godoy, Tomás Fernando; Kaufmann, Uriel (2014)Let Ω be a smooth bounded domain in RN and let m be a possibly discontinuous and unbounded function that changes sign in Ω. Let f : [0,∞) → [0,∞) be a nondecreasing continuous function such that k1 ξp ≤ f (ξ) ≤ k2 ξp for ... -
Strictly positive solutions for one dimensional nonlinear elliptic problems
Kaufmann, Uriel; Medri, Iván Vladimir (2014)We study the existence and nonexistence of strictly positive solutions for the elliptic problems -- in a bounded open interval, with zero boundary conditions, where -- is a strongly uniformly elliptic differential operator, ...
