Most US universities and colleges have been closed by cautionary measures attempting to slow down the spread of COVID19 through our communities. For most of us, this meant that we had to hastily adjust to teaching and/or taking our classes remotely. As for day-to-day research, although suddenly the time for engaging with it shrank, the logistics remained similar: have been manuscripts flowing through Google Drive/Dropbox/GitHub/Overleaf repositories, reviews and revisions have been flowing through online submission systems for decades, and we have been checking-in with remote collaborators via Skype/Zoom/Google Hangouts for years now. (Remote collaborators do now include graduate students and graduate advisors, suddenly.)
What about research talks and colloquia? If your Department is as ours, there is one time of the week where most faculty and graduate students have a slot freed up in their schedules to grab a cup of tea/coffee, a cookie/fruit, and settle into a classroom to listen to the visiting speaker. We remind ourselves that we are a part of a research community that is both local (your neighbors in the hallway) and global (the person who traveled all this way to see you).
Thankfully, there are many research talks that also migrated online, perhaps unsurprisingly so. We bring here a short list of some talk series that have gone online. If you find that this is a good resource, others may agree: ask your department colleagues if they would be interested in setting up a time in the week for "joint viewing" of a chosen talk, with a time for discussion after the talk.
And of course if you are not particular about live/recent talks, you can browse through lecture repositories of several institutes and societies:
Finally: If you are following or organizing a seminar and want it listed, please email a link to DSWeb ([email protected]). Until we can all share a room together and get lost in mathematics, perhaps online seminars can serve as a good substitute in these socially-distant times.
