December 19, 2018## Special Session

October 22, 2018Two pictures from last weekend’s Session.

We rescued this one from Instagram a couple of minutes after it happened (Paul noticed that #determinacy was missing from the list):

And a decent group picture. Missing: Maryanthe Malliaris (who took it), Harry Altman and Jeffrey Bergfalk:

Many thanks to all the participants, and to the AMS for making it possible.

## Open house

October 4, 2018Mathematical Reviews will have an open house at the upcoming AMS meeting here in Ann Arbor. There will be some snacks, at the very least. The event will take place Saturday October 20, 12:30-2:00 pm at 416 Fourth Street.

For some of the history of the building and a few pictures, see here.

## Professorship in Logic at the University of Vienna

February 4, 2018I have been asked to help spread the word. Sy Friedman, the head of the Kurt Gödel Research Center at the University of Vienna (where I had my first postdoc), is retiring, and there is a search underway for a replacement. The KGRC has been significant in fostering a multitude of early career researchers in set theory, and it would be a shame if the position ended up in another discipline.

If you are interested, please consider applying. If you know of someone who may be interested, please help spread the word. The deadline is April 15.

From the link, the position is for a “University Professor of Mathematical Logic Taking into Account the Foundations of Computer Science”. Applications should be submitted by e-mail to the Dean of the Faculty of Mathematics of the University of Vienna, Univ.-Prof. Dr. Christian Krattenthaler, Oskar-Morgenstern-Platz 1, 1090 Vienna (dekanat.mathematik@univie.ac.at). Further details are at the link.

## Monica Agana – The classical theory of rearrangements

July 16, 2017Monica was my last masters student at Boise State, completing her thesis in December 2015, while I was already at Mathematical Reviews. My colleague at Boise State Zach Teitler coadvised her for the last few months. The following picture is from graduation day.

Monica’s thesis, *The classical theory of rearrangements*, discusses Riemann’s famous rearrangement theorem for conditionally convergent series of real numbers, prior results, and some extensions and related topics. This previous blog post discusses some of these.
