On the convexity of the function C --> f(det C) on positive definite matrices
Stephan Lehmich, Patrizio Neff, Johannes Lankeit
We prove a condition on f \in C^2(\R+,\R) for the convexity of (f o det) on PSym(n), namely that f o det is convex on PSym(n) if and only if f"(s)+(n-1)/(ns) f'(s) >= 0 and f'(s)<=…

Existence theorems in the geometrically non-linear 6-parametric theory of elastic plates
Mircea Birsan, Patrizio Neff
In this paper we show the existence of global minimizers for the geometrically exact, non-linear equations of elastic plates, in the framework of the general 6-parametric shell the…
