Topologies related to (I)-envelopes
Ondřej F. K. Kalenda, Matias Raja
We investigate the question whether the (I)-envelope of any subset of a dual to a Banach space may be described as the closed convex hull in a suitable topology. If contain…

Ergodicity and super weak compactness
Guillaume Grelier, Matías Raja
We prove that a closed convex subset of a Banach space is (super-)weakly compact if and only if it is (super)-ergodic. As a consequence we deduce that super weakly compact sets are…
