Structure of the Set of Norm-attaining Functionals on Strictly Convex Spaces
Let X be a separable non-reflexive Banach space. We show that there is no Borel class which contains the set of norm-attaining functionals for every strictly convex renorming of X....

Affine trajectories in a field of strictly convex functions
The paper presents one important and interesting property of strictly convex functions. On the base of previously proved properties of these functions, we can generalize some global-geometric conclusions, without t...

Strictly convex renormings
A normed space X is said to be strictly convex if x = y whenever //(x+y)/2 admit an equivalent strictly convex norm. We present a characterization in linear topological terms of the normed spaces which are stri...

A strictly convex Sobolev function with null Hessian minors
Given 1 LESS-THAN OR EQUAL TO p < k LESS-THAN OR EQUAL TO n, we construct a strictly convex function f ELEMENT OF W^{2,p}((0,1)^n) with α-Hölder continuous TO k, and rank NABLA^2 g < k a.e., then g cannot be strictly

On minimization of multivariate entropy functionals
The problem of minimizing convex integral functionals subject to moment-like constraints is treated in a general setting when the underlying convex function may be multivariate, perhaps not strictly co...

Convex programming with separable ellipsoidal constraints: application in contact problems with orthotropic friction
The algorithm for constrained minimization of strictly convex quadratic functions subject to simple bounds and separable ellipsoidal constraints is used for numerical solution of discretized 3D contact problems with orthotr...

On a Neumann problem for variational functionals of linear growth
We consider a Neumann problem for strictly convex variational functionals of linear growth. We establish the existence of minimisers among W1,1- functions, in this situation, the relaxation of the functional
