Concentration Week on Ideals and Algebras of Operators and SUMIRFAS
by Pavlos Motakis 31 May '23

31 May '23

Dear all, This is a registration call for the “Concentration Week on Ideals and Algebras of Operators<https://sites.google.com/view/ideals-algebras-banach/home-registration?auth…>” between July 24-28 and SUMIRFAS<https://www.math.tamu.edu/conferences/functional_analysis/sumirfas.html> between July 28-30. Both events will take place in person in College Station, Texas, and are part of the “Workshop in Analysis and Probability<https://www.math.tamu.edu/conferences/functional_analysis/PANEM.html>” of Texas A&M University. The registration is available at the following link until June 15: https://docs.google.com/forms/d/e/1FAIpQLSfH17cKAoMG48PFxT8DcB8I2s7BCLhwyWU… The Concentration Week on Ideals and Algebras of Operators is intended to bring together researchers interested in the various aspects of spaces of operators in Banach spaces. Particular emphasis is given to the rich theory induced by quotients over classical ideals as well as by the plenitude of different ideals. The purpose is to showcase and bring together cutting-edge technologies in constructing and studying ideals in the algebras of bounded linear operators on classical and non-classical spaces, draw parallels to the study of C* and operator algebras, and set the tone for future research directions in the field. We also welcome researchers interested in the interactions between other fields (logic, set theory, homological algebra, topology) and various aspects of algebras of operators. There is no registration fee and hotel costs will be directly covered by the conference. Your hotel room will be booked for you, and all rooms will be single occupancy. In the registration form, you will be asked for check-in and check-out dates between July 5 and July 31. Graduate students whose institution or advisor cannot support their travel may apply for travel funding. Some restrictions apply. On behalf of the organizers, -- Pavlos Motakis Assistant Professor Department of Mathematics and Statistics York University Office: S618 Ross Webpage: https://pmotakis.mathstats.yorku.ca/

Banach spaces webinar on Friday 5/12 by Bruce Blackadar
by Sari, Bunyamin 10 May '23

10 May '23

Hi all, Please join us for the following talk on Friday 5/12 at 9am (Central) . Zoom link: https://unt.zoom.us/j/86396583011 Hilbert Spaces Without Countable AC Bruce Blackadar (University of Nevada, Reno) Abstract: This article examines Hilbert spaces constructed from sets whose existence is incompatible with the Countable Axiom of Choice (CC). Our point of view is twofold: (1) We examine what can and cannot be said about Hilbert spaces and operators on them in ZF set theory without any assumptions of Choice axioms, even the CC. (2) We view Hilbert spaces as ``quantized'' sets and obtain some set-theoretic results from associated Hilbert spaces.

Banach spaces webinar by Anna Pelczar-Barwacz (Jagiellonian) on Friday May 5th
by Sari, Bunyamin 01 May '23

01 May '23

Hi all, Please join us for the following talk on Friday May 5th at 9am (central). The zoom link: https://unt.zoom.us/j/88959687677 Best, Bunyamin A Banach space with an infinite dimensional reflexive quotient operator algebra L(X)/SS(X) Anna Pelczar-Barwacz (Jagiellonian) Abstract. I will discuss method of constructing a Banach space X such that the algebra of bounded operators L(X) is a direct sum of an infinite dimensional reflexive Banach space V and the operator ideal of strictly singular operators SS(X). The space V is spanned by an unconditional basic sequence (I_s)_{s=0}^\infty where I_0 is the identity on X, whereas each I_s, s=1,2,... is a projection on some subspace X_s of X. The multiplication on V is defined naturally: V is the unitization of the subalgebra of L(X) spanned by (I_s)_{s=1}^\infty with the pointwise multiplication. https://researchseminars.org/talk/BanachWebinars/77/
