  • Research seminar "Asymptotics, operators and functionals'': Mondays at 16:15-18:15 in Wolfson Lecture Theatre 4W 1.7.

    We aim to discuss the latest results and techniques in the asymptotic analysis of operators, differential equations and functionals, as well as its applications to mechanics, materials and wave propagation. The talk will usually focus on one or two aspects of a problem of current interest, and is meant to form the basis for an informal discussion during and after the talk. All welcome.

    Next talk is by Igor Velčić (Zagreb) on 26 September 2016. Please note change of venue: 1W2.03
