On Daugavet indices of thickness
Rainis Haller, Johann Langemets, Vegard Lima +2
Inspired by R. Whitley's thickness index the last named author recently introduced the Daugavet index of thickness of Banach spaces. We continue the investigation of the behavior o…

Symmetric strong diameter two property
Rainis Haller, Johann Langemets, Vegard Lima +1
We study Banach spaces with the property that, given a finite number of slices of the unit ball, there exists a direction such that all these slices contain a line segment of lengt…

Stability of average roughness, octahedrality, and strong diameter 2 properties of Banach spaces with respect to absolute sums
Rainis Haller, Johann Langemets, Rihhard Nadel
We prove that, if Banach spaces and are -average rough, then their direct sum with respect to an absolute norm is -average rough. In particular, for octahe…
