Computing Wasserstein Barycenter via operator splitting: the method of averaged marginals

Autor: Mimouni, Daniel, Malisani, P, Zhu, J., de Oliveira, W.

The Wasserstein barycenter (WB) is an important tool for summarizing sets of probability measures. It finds applications in applied probability, clustering, image processing, etc. When the measures' supports are finite, computing a (balanced) WB can

Percolation on Lieb lattices

Autor: Oliveira, W. S., de Lima, J. Pimentel, Costa, Natanael C., Santos, R. R. dos

We study site- and bond-percolation on a class of lattices referred to as Lieb lattices. In two dimensions the Lieb lattice (LL) is also known as the decorated square lattice, or as the CuO$_2$ lattice; in three dimensions it can be generalized to a
