Postdoc Seminars

IMA Postdoc Seminars are given weekly throughout the fall and spring semesters. Postdocs present on a variety of mathematical topics that may be unrelated to the current annual program theme. IMA visitors and University of Minnesota faculty are also invited to present on subjects of interest.

Andy Thaler and Weiwei Hu of the University of Minnesota will be organizing the 2015-2016 seminar series.

Titles, abstracts, and speakers for each seminar will be posted as available. All seminars are from 2:25pm - 3:25pm unless otherwise noted.

    We will present minimization problems arising from Elasticity Theory with total lack of coercivity and convexity. Yet, duality and uniqueness result will be discussed.
  • Decentralised Stability Guarantees for Electrical Power Systems

    We give an overview of a technique for analysing the performance of large dynamical networks, such as electrical power systems. The technique can be used to guarantee that a certain level of performance is achieved by the network on the basis of a set of low complexity decentralised tests. These tests are robust to structural changes within the network, and can also be used to guide the design of local control systems. The conditions are used to demonstrate that the oscillatory modes within a benchmark power system model are sufficiently well damped. The analysis is then extended to provide the same guarantees for power systems models of arbitrary size.
