For Spring 2022: Workshop on C*-algebras: Structure and Dynamics, 16--19 May 2022, at Sde Boker, Israel. It is very likely that this multiply postponed conference now really will take place at the time given. In particular, tourists are now being allowed to enter Israel, with a negative PCR test not more than 72 hours before departure.

Teaching for Fall 2022, Winter 2023, and Spring 2023 to be posted when I know what it is.

Notes on crossed product C*-algebras and minimal dynamics. This version has been submitted for publication, but still contains misprints (probably many misprints).

Shanghai short course on crossed products by finite group actions on C*-algebras (11--20 July 2016).

Wyoming short course on large subalgebras and the structure of crossed products. Slides and a draft of the lecture notes are posted.

Shanghai short course on crossed products by finite group actions on C*-algebras (26--30 July 2014).

Summary of results on L^p operator algebras which "look like" C*-algebras (GPOTS 2014) (pdf)

Block "scientific spammers" with the Scientific Spam DNSBL. It should, for example, block many of the predatory open access "journals" (see lists of publishers, individual journals (apparently standalone), and "hijacked journals", which pretend to be real journals but will publish almost anything (even "papers" generated at random by a computer) if paid a high fee. (The original version was Beall's list; unfortunately no longer maintained; original location.) To request that the University of Oregon implement the Scientific Spam DNSBL, email techdesk@uoregon.edu.

I am a Professor in the Mathematics Department at the University of Oregon. My research specialty is operator algebras. I maintain an operator algebraist email directory, whose updates carry announcements of interest to operator algebraists, and a page of WWW operator algebra resources. I also maintain several web pages with information for people attending conferences at the Mathematics Department at the University of Oregon; details here.

During the winter quarter 2014, I was at the University of Toronto, where I taught a course on crossed products of C*-algebras and Banach algebras.

I remain involved with the organization of the West Coast Operator Algebra Seminars (WCOAS).

Here are the locations of the next several: Sign up for future information by joining the WCOAS confirmed opt-in mailing list.

RIMS Winter School lectures.

CRM course.

Slides from my talk "Towards the classification of outer actions of finite groups on Kirchberg algebras" at the Centre de Recerca Matematica, Universitat Autonoma de Barcelona, June 2011.

Slides from my talk "Strict comparison for crossed products by free minimal actions of Z^d" at the Research Institute for Mathematical Sciences, Kyoto University, September 2011.

In June 2009, I gave a one week course on crossed product C*-algebras, at the International Summer School on Operator Algebras and Applications in Lisbon, Portugal. A draft of a related set of lecture notes is available on the course page.

Lectures at the Shanghai Special Week on Operator Algebras.

In December 2009, I gave a short course on crossed product C*-algebras, Seoul National University. A draft of a related set of lecture notes is available on the course page, and files of the slides used have been posted there.

Current interest: Examples of "quasilegitimate" spammers (real organizations or selling otherwise legitimate products) who ought to be blocked.
