Some lifting and approximation properties for maps in
André Guerra, Xavier Lamy, Konstantinos Zemas
Smooth maps can be lifted to using the Hopf fibration via the factori…
Atomic Gradient Flows: Gradient Flows on Sparse Representations
Christian Amend, Marcello Carioni, Konstantinos Zemas
One of the most popular approaches for solving total variation-regularized optimization problems in the space of measures are Particle Gradient Flows (PGFs). These restrict the pro…
Global minimality of the Hopf map in the Faddeev-Skyrme model with large coupling constant
André Guerra, Xavier Lamy, Konstantinos Zemas
We prove that, modulo rigid motions, the Hopf map is the unique minimizer of the Faddeev--Skyrme energy in its homotopy class, provided that the radius of the target 2-sphere is no…
Derivation of Kirchhoff-type plate theories for elastic materials with voids
Manuel Friedrich, Leonard Kreutz, Konstantinos Zemas
We rigorously derive a Blake-Zisserman-Kirchhoff theory for thin plates with material voids, starting from a three-dimensional model with elastic bulk and interfacial energy featur…
On the existence of degenerate solutions of the two-dimensional -system
André Guerra, Xavier Lamy, Konstantinos Zemas
We consider entire solutions of the -system which we refer to as bubbles. Surprisingly, and contrary to conjectures r…
Energy barriers for boundary nucleation in a two-well model without gauge invariance
Antonio Tribuzio, Konstantinos Zemas
We study energy scaling laws for a simplified, singularly perturbed, double-well nucleation problem confined in a half-space, in the absence of gauge invariance and for an inclusio…
