  2. RAS/DDC - Career Development Panel with Murray Cantor: The joys of industrial mathematics

    Location: MSRI: Online/Virtual
    Speakers: Murray Cantor (University of California, Berkeley)

    After about five years in academia, with NSF grants, a bunch of publications, and a couple of awards for my articles, I realized that the academic life didn’t work for me personally or intellectually. So, I reinvented myself as an industrial mathematician.

    I am glad I did I made the transition. I have worked on some very interesting projects in a wide range of fields. I have the enjoyed seeing my work having practical impact. And, I have had great colleagues and get to mentor some very some intelligent and motivated junior staff.


    In this discussion, I will share some of my industry experiences, lessons learned about the industrial mindset, and some of the current math problems being tackled today by industry.

  3. DDC - Valuation Theory: Real differential forms and currents on non-archimedean spaces, reloaded

    Location: MSRI: Online/Virtual
    Speakers: Antoine Chambert-Loir (Institut de Mathematiques de Jussieu)

    Valuation theory plays a major part in the interaction between number theory and logic. In this seminar, a variety of topics from valuation theory, and in particular connections to model theory, will be discussed. There will be a strong emphasis on results involving the definability of valuations.

    I will describe some aspects of joint work with Antoine Ducros (https://arxiv.org/abs/1204.6277) where we define, for the non-archimedean analytic spaces of Berkovich, an analogue of the classical calculus of differential forms and currents on complex analytic manifolds. A first version of the theory appeared on arXiv in 2012, and I will try to emphasize aspects which emerged since we started to revise this still unpublished manuscript. Besides the complex analytic picture which is used as a guide throughout our work, the theory is built on ideas from tropical geometry, a construction of A. Lagerberg on R^n, and on the presence, within non-archimedean spaces, of polyhedral real subspaces (skeleta) on which real calculus can be performed.
