Diameter two properties for spaces of Lipschitz functions

Rainis Haller, Andre Ostrak, Märt Põldvere

We solve some open problems regarding diameter two properties within the class of Banach spaces of real-valued Lipschitz functions by using the de Leeuw transform. Namely, we show…

The Lipschitz-free space over length space is locally almost square but never almost square

Rainis Haller, Jaan Kristjan Kaasik, Andre Ostrak

We prove that the Lipschitz-free space over a metric space M is locally almost square whenever M is a length space. Consequently, the Lipschitz-free space is locally almost square…

On the duality of the symmetric strong diameter 2 property in Lipschitz spaces

Andre Ostrak

We characterise the weak∗ symmetric strong diameter 2 property in Lipschitz function spaces by a property of its predual, the Lipschitz-free space. We call this new property d…

Characterisation of the weak-star symmetric strong diameter 2 property in Lipschitz spaces

Andre Ostrak

We give a characterisation of the weak* symmetric strong diameter 2 property for Lipschitz function spaces in terms of a property of the corresponding metric space. Using this char…
