The London PDE Seminar is a London-based seminar featuring speakers at the forefront of mathematical research in partial differential equations.
Upcoming Seminars
The seminar convenes fortnightly, on approximately every other Friday.
Some talks will be held in-person, while others will be held on Zoom.

Title: Weakly hyperbolic systems with singular coefficients
Abstract:
In this talk, I will present recent work conducted with Claudia Garetto on hyperbolic systems with non-diagonalizable principal parts, multiplicities, and singular coefficients (arXiv:2305.12832).
This research builds upon the analysis of hyperbolic systems with non-diagonalizable principal parts and variable multiplicities, which was initiated by Gramchev and Ruzhansky in 2013 for 2x2 hyperbolic systems.
The work was later extended by Garetto, Jäh, and Ruzhansky in 2018 to systems of arbitrary size.
In our study, we assume that the system has either discontinuous coefficients or, more generally, distributional coefficients.
We prove well-posedness in a very weak sense for systems with singularities, either with respect to the space variable or the time variable.
