SUMMARY:Workshop / Seminar:DE Seminar: The Guderley Problem: Existence of Self-Similar Shock Solutions
DESCRIPTION:Dating back to Guderley’s pioneering work in 1942\, the Guderley problem is a classical problem in compressible fluid dynamics describing the implosion and subsequent reflection of a strong spherical shock wave. An initially converging shock propagates toward the origin\, strengthens as it collapses\, and eventually develops a singularity. After the collapse\, an outgoing shock emerges and propagates outward.\n\nIn this talk\, I will present our rigorous construction of self-similar converging and diverging shock solutions for the adiabatic exponent $\gamma\in(1\,3]$. These solutions are analytic away from the shock interfaces and the blow-up point. The proof relies on continuity arguments\, nonlinear invariances\, and barrier functions.

SUMMARY:Workshop / Seminar:EEB Thursday Seminar Series - The old field rules: the quest to develop generalizable principles about how ecosystems function
DESCRIPTION:Seminar Summary - The presentation will chronicle a journey of long-term research devoted to discovering fundamental principles—rules of life—that explain how animal species’ adaptive evolutionary ecological interactions determine how they control ecosystem functioning. I will discuss how this research journey led to systematic resolution of generalizable principles that explain how ecosystems function. The fundamental lesson is that dedication to long-term theory-informed field research can lead to a coherent predictive understanding of how ecosystems function.
