As a consequence of our main results, we prove that the condition $\gamma<2$ is necessary and sufficient for the existence of solutions in $H^1_0(\Omega)$ for every sufficiently regular $f$ as above. es_ES dc.language.iso en es_ES dc.publisher Elsevier es_ES dc.subject Matemáticas es_ES dc.title Existence and nonexistence of solutions for singular quadratic quasilinear equations es_ES dc.type info:eu-repo/semantics/article es_ES dc.relation.publisherversion http://dx.doi.org/10.1016/j.jde.2009.01.016 es_ES dc.rights.accessRights info:eu-repo/semantics/openAccess es_ES
