Yair Hayut - Stationary reflection at $\aleph_{\omega+1}$
Talk held by Yair Hayut (Hebrew University of Jerusalem, Israel) at the KGRC seminar on 2018-05-17. Abstract: Stationary reflection is one of the basic prototypes of reflection phenomena, and its failure is related to many counterexamples for compactness properties (such as almost free non-free abelian groups, and more). In 1982, Magidor showed that it ...

## A Mastodon instance for academics

Scholar Social is meant for: researchers, grad students, librarians, archivists, undergrads, academically inclined high schoolers, educators of all levels, journal editors, research assistants, professors, administrators—anyone involved in academia who is willing to engage with others respectfully.

We strive to be a safe space for queer people and other minorities, recognizing that there can only be academic freedom where the existence and validity of interlocutors' identities is taken as axiomatic.

"A Mastodon profile you can be proud to put on the last slide of a presentation at a conference"

## "Official" monthly journal club!

(Participation is, of course, optional)

Scholar Social features a monthly "official" journal club, in which we try to read and comment on a paper of interest.

Any user of Scholar Social can suggest an article by sending the DOI by direct message to @socrates@scholar.social and one will be chosen by random lottery on the last day of the month. We ask that you only submit articles that are from *outside* your own field of study to try to ensure that the papers we read are accessible and interesting to non-experts.
