We prove the existence of a double infinite sequence of radial solutions for a Dirichlet concave-convex problem associated with an elliptic equation in a ball of R n . We are interested in relaxing the classical positivity condition on the weights, by allowing the weights to vanish. The idea is to d

## Abstract We investigate some geometric properties of level sets of the solutions of parabolic problems in convex rings. We introduce the notion of __parabolic quasi‐concavity__, which involves time and space jointly and is a stronger property than the spatial quasi‐concavity, and study the conve
