A Dirichlet problem on the half-line for nonlinear equations with indefinite weight

Zuzana Došlá, Mauro Marini, Serena Matucci

We study the existence of positive solutions on the half-line $[0,\infty )$ for the nonlinear second order differential equation \[ \bigl(a(t)x^{\prime}\bigr)^{\prime}+b(t)F(x)=0,\q…
