Schauder bases in Lipschitz free spaces over nets in Banach spaces

Petr Hájek, Rubén Medina

In the present note we give two explicit constructions (based on a retractional argument) of a Schauder basis for the Lipschitz free space F(N), over certain uniformly…

Lipschitz retractions and complementation properties of Banach spaces

Petr Hájek, Andrés Quilis

In the present paper we introduce and study the Lipschitz retractional structure of metric spaces. This topic was motivated by the analogous projectional structure of Banach spaces…

Compact retractions and Schauder decompositions in Banach spaces

Petr Hájek, Rubén Medina

In our note we show the very close connection between the existence of a Finite Dimensional Decomposition (FDD for short) for a separable Banach space X and the existence of a Li…

Projecting Lipschitz functions onto spaces of polynomials

Petr Hájek, Tommaso Russo

The Banach space P(2X) of 2-homogeneous polynomials on the Banach space X can be naturally embedded in the Banach space Lip0​(BX​) of real-valued Lipsc…
