You can't always get what you want - Regularity and Singularity in Nonlinear PDE
This is a talk in the Mathematical Colloquium series of the Winter Semester 2026/27, discussing questions of regularity versus singularity formation in nonlinear partial differential equations — i.e., when solutions to nonlinear PDEs behave smoothly and predictably versus when they develop singularities (playfully nodding to the Rolling Stones' song "You Can't Always Get What You Want").
