Determination of (unbounded) convex functions via Crandall-Pazy directions
Aris Daniilidis, David Salas, Sebastián Tapia-García
It has been recently discovered that a convex function can be determined by its slopes and its infimum value, provided this latter is finite. The result was extended to nonconvex f…

A slope generalization of Attouch theorem
Aris Daniilidis, David Salas, Sebastián Tapia-García
A classical result of variational analysis, known as Attouch theorem, establishes the equivalence between epigraphical convergence of a sequence of proper convex lower semicontinuo…

Steepest geometric descent for regularized quasiconvex functions
Aris Daniilidis, David Salas
We establish existence of steepest descent curves emanating from almost every point of a regular locally Lipschitz quasiconvex functions, where regularity means that the sweeping p…
