If you are a mathematician interested in visiting me and Oxford for a short visit, please contact me. My research group has some funding available.

Workshop “DG-enhancements and higher category methods” Mon 8th - Fri 12th December 2014, University of Warwick

See more information about this exciting workshop here:
I was supposed to go to Oxford a few weeks ago for the beginning of term, but I could not because of the policies of UKVI (United Kingdom Visas and Integration) which imposes a one year waiting period between visas. I am hoping that they will give me back my passport with a visa soon. It takes over a thousand dollars and two months to apply for a visa.

YRM 2015 is coming to Oxford!

Following an enormously successful YRM at the University of Warwick last week, we are pleased to announce that YRM 2015 will be held at the University of Oxford, in the new Andrew Wiles building.

Launched at the University of Cambridge in 2009, Young Researchers in Mathematics (YRM) is an annual conference for doctoral and post-doctoral students in the UK. There are streams of talks covering almost all areas of research mathematics, and, in this and previous years, the conference has attracted large numbers of students from all across the UK and several parts of Europe. It offers the opportunity for all participants to speak, as well as featuring plenary speakers and keynote talks from leading mathematicians in each of the main streams.

YRM 2015 will be held Monday-Thursday of the week beginning 17th August 2015. Please share this with research students at your university, in order that they may save the date!

I am currently at an exciting conference organized by Ivan Fesenko together with Kobi Kremnizer and Boris Zilber. My hat goes of to Ivan Fesenko for bringing together such an esteemed group of his colleagues and other mathematicians for this amazing conference. See more about it on Ivan's homepage at I am also happy to see many familiar faces from Gaitsgory's epic conference in Jerusalem on the Geometric Langlands conjectures. Unfortunately, this past few months have been so busy that I have not been able to record my perceptions on that amazing conference in blog form. Here is a link to that:

I recently had the chance to speak at a small, intimate conference organized by Francesco Baldassarri at the university of Padova alongside the thesis defence of Federico Bambozzi. Here is the list of topics from the Padova conference:

The Penn math department expanded and improved its space for visitors in the last few years. Here is a view of the snowstorm from the window of the beautiful new visitor's office.

If you are in Philadelphia be sure to check out the Deformation Theory Seminar at Penn. Organized by Jim Stasheff, it features both young mathematicians and also seasoned veterans. Murray Gerstenhaber (a Penn professor) is a regular at this seminar. Another exciting Penn seminar is the Galois Seminar where you will find C.-L. Chai, T. Chinburg,  D. Harbater and F. Pop. This is in general a very curious audience and there are always lively conversations.

Its been a busy semester and between the semesters I will be doing some travelling. I just got back from a beautiful visit to Israel's newest university: Ariel University where I gave a talk in the math department. I am planning upcoming trips to UPenn to meet with Tony Pantev, Jonathan Block, Ron Donagi, Jim Stasheff and David Harbater. Then I will visit the IAS and meet Chris Brav and Vladimir Berkovich. I will then visit Oxford briefly to meet with Lino Amorim, Konstantin Ardakov, Kobi Kremnizer and Dominic Joyce. Finally, I will go to the University of Padova, (former employer of Galileo Galilei) to attend Higher structures in algebraic analysis and meet with Francesco Baldassarri and his student Federico Bambozzi. 
The "Motivic invariants and categorification" EPSRC Programme Grant research group at Oxford held a workshop on Monday 7 October - Wednesday 9 October. Talks were given by Emily CliffDennis BorisovOren Ben-Bassat, Dario Beraldo,  Robert Laugwitz, Vittoria Bussi, Kobi Kremnizer, Balazs Szendroi, Dominic Joyce and Yan Ting Lam. Dominic gave an overview of his research program and his slides are available at this link.

Here are the titles of the talks

First Post

Hello world. We are entering an age where the distinction between human, computer and internet is fading away. In an effort to fully participate in the new global consciousness or 'being' which is forming, we will publish in this blog various thoughts on mathematics and perhaps more. Although much of what we say may be incomprehensible to non-mathematicians, we may try here and there to communicate something about the experience of mathematics, and maybe a little about the objects we try to understand. Pictures from around the world will also be posted (including pictures from various mathematical conferences). Oren Ben-Bassat, Jan. 2, 2014, Tel Aviv.
