A Banach space with an unconditional basis which is not slicely countably determined
Marcus Lõo, Yoël Perreau
In this note, we study the geometry of the unit ball of the Banach space generated by the adequate family of all subsets of branches of the infinite binary tree, and answer several…

The super Alternative Daugavet property for Banach spaces
Johann Langemets, Marcus Lõo, Miguel Martín +2
We introduce the super alternative Daugavet property (super ADP) which lies strictly between the Daugavet property and the Alternative Daugavet property as follows. A Banach space…

Slicely countably determined points in Banach spaces
Johann Langemets, Marcus Lõo, Miguel Martin +1
We introduce slicely countably determined points (SCD points) of a bounded and convex subset of a Banach space which extends the notions of denting points, strongly regular points…
