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

## Abstract Given a __C__^2^ function __u__, we consider its quasiโconvex envelope __u__\* and we investigate the relationship between __D__^2^__u__ and __D__^2^__u__\* (the latter intended in viscosity sense); we obtain two inequalities between the tangential Laplacian of __u__ and __u__\* and the
