On the concave one-dimensional random assignment problem and Young integration theory

Michael Goldman, Dario Trevisan

We investigate the one-dimensional random assignment problem in the concave case, i.e., the assignment cost is a concave power function, with exponent , of the distance betw…

From energy bounds to dimensional estimates in a branched transport model for type-I superconductors

Guido De Philippis, Michael Goldman, Berardo Ruffini

We consider a branched transport type problem which describes the magnetic flux through type-I superconductors in a regime of very weak applied fields. At the boundary of the sampl…

A deformation theorem for tensor flat chains and applications (complement to ''Tensor rectifiable G-flat chains'')

Michael Goldman, Benoît Merlet

In this note we extend White's deformation theorem for G-flat chains to the setting of G-flat tensor chains. As a corollary we obtain that the groups of normal tensor chains identi…

Set-decomposition of normal rectifiable G-chains via an abstract decomposition principle

Michael Goldman, Benoît Merlet

We introduce the notion of set-decomposition of a normal G-flat chain. We show that any normal rectifiable -flat chain admits a decomposition in set-indecomposable sub-chains. T…

Rigidity of the ball for an isoperimetric problem with strong capacitary repulsion

Michael Goldman, Matteo Novaga, Berardo Ruffini

We consider a variational problem involving competition between surface tension and charge repulsion. We show that, as opposed to the case of weak (short-range) interactions where…

Compactness and structure of zero-states for unoriented Aviles-Giga functionals

Michael Goldman, Benoit Merlet, Marc Pegon +1

Motivated by some models of pattern formation involving an unoriented director field in the plane, we study a family of unoriented counterparts to the Aviles-Giga functional. We in…
