Dear all, The next Banach spaces webinar is on Friday October 2 9AM CDT (e.g., Dallas, TX time). Please join us at https://unt.zoom.us/j/512907580 Speaker: Anna Pelczar-Barwacz, Jagiellonian University Title: Small operator ideals on the Schlumprecht and Schreier spaces Abstract. I report on the joint work with Antonis Manoussakis, showing that there are $2^{2^{\aleph_0}}$ many different closed operator ideals on the Schlumprecht space and every Schreier space of finite order admits a chain of the cardinality $2^{\aleph_0}$ of closed operator ideals.
