AMCS seminar on Quasiconvex Elastodynamics: weak-strong uniqueness for measure-valued solutions

Start Date: November 14, 2017
End Date: November 14, 2017

By Professor Konstantinos Koumatos (University of Sussex, UK)
A weak-strong uniqueness result is presented for dissipative measure-valued solutions to the system of conservation laws arising in elastodynamics. The main novelty of this work is that the underlying stored-energy function is assumed strongly quasiconvex. The proof borrows tools from the calculus of variations to prove convexity type bounds for quasiconvex functions, and recasts them to adapt the relative entropy method to quasiconvex energies.
Biography: Konstantinos Koumatos is a Lecturer in Mathematics at the University of Sussex, UK and his research lies in nonlinear analysis with an emphasis on problems arising in solid mechanics and materials science. He earned his PhD at the University of Oxford in 2012 under the supervision of Professor Sir John Ball where he remained as a postdoctoral researcher until 2014. Between 2014-2016 and prior to joining Sussex, he worked at the Gran Sasso Science Institute in L’Aquila, Italy.
