The next meeting of the Algebra and Logic Seminar will be held in hybrod format (in Room 578 of IMI – BAS and online via Zoom) on November 10, 2023 (Friday) at 1:00 pm (UTC+2).
A talk on:
Transfinite version of the Mittag-Leffler condition for the vanishing of the derived limit
will be delivered by
Mishel Carelli (Technion – Israel Institute of Technology, Israel).
Abstract.We give a necessary and sufficient condition for an inverse sequence S0 ← S1 ← . . . indexed by natural numbers to have lim¹S = 0. This condition can be treated as a transfinite version of the Mittag-Leffler condition. We consider inverse sequences in the category of abelian groups. We also show that the class of inverse sequences S such that lim S = lim¹S = 0 is the least class of inverse sequences containing the trivial inverse sequence and closed with respect to small limits and a certain type of extensions.
