We revisit some results obtained by the authors together with Fabio Zanolin about the existence and multiplicity of positive solutions of boundary value problems associated with second-order equations of the type u''+q(t)g(u)=0, where q is a sign-changing weight and g is a non-negative nonlinear function.
