Mathematical Colloquium, "Logarithmic norms and Quadratic forms", Gustaf Söderlind (University of Lund)
Gustaf Söderlind (University of Lund)
Title: Logarithmic norms and Quadratic forms
The logarithmic norm was introduced in 1958 for matrices, for the purpose of estimating growth rates in initial value problems. Since then, the concept has been extended to spectral theory, nonlinear maps, differential operators and function spaces. There are applications to operator equations in general, including evolution equations as well as boundary value problems and PDEs. A broad introduction to the topic will be given, demonstrating the recurring pattern found in various applications.
