A relaxed-pace seminar on impromptu subjects related to the interests of the audience. Everyone is welcome. The subjects are geometry, probability, combinatorics, dynamics, and more!

Multiple Dirichlet series are meromorphic functions in  several complex variables developed in analytic number theory to study moments of L-functions. Nichols algebras are noncommutative algebras developed to study Hopf algebras and quantum groups. In joint work in progress with Ian Whitehead, we give a uniform construction of multiple Dirichlet series in the function field setting, unifying many previous constructions and producing new examples. I will give an introduction to these two areas and explain how our work relates them.
