Título: Projections in Lipschitz-free spaces induced by group actions

Resumo:  I will talk about a new method of constructing a projection in Lipschitz-free spaces based on continuous actions of amenable groups on metric spaces. One of the outcomes is that given a compact group G acting by isometries on a metric space M, the Lipschitz-free space over the space of orbits M/G (endowed with Hausdorff distance) is complemented in the Lipschitz-free space over M. The talk will be based on a recent work with M. Doucha (https://arxiv.org/abs/2104.11519).
