We consider a general class of eigenvalue problems where the leading elliptic term corresponds to a convex homogeneous energy function that is not necessarily differentiable. We derive a strong maximum principle and show uniqueness of the first eigenfunction. Moreover we prove the existence of a sequence of eigensolutions by using a critical point theory in metric spaces. https://www.ealisboa.com/deal-find-Orca-Vape-x-Suicide-Mods-Stubby-MTL-Conversion-Kit-huge-savings/
