Partial regularity for $A$ -quasiconvex variational problems of linear growth

Christopher Irving, Zhuolin Li, Bogdan Raiţă

We prove that minimizers of variational integrals $E (v) = \int_{Ω} f (v) for v \in M (Ω) such that A v = 0,$ are partially continuous provid…

Universality of renormalisable mappings in two dimensions: the case of polar convex integrands

Christopher Irving, Benoît Van Vaerenbergh

We establish universality of the renormalised energy for mappings from a planar domain to a compact manifold, by approximating subquadratic polar convex functionals of the form $\i…
