Abstract:
We study the variational wave equation subject to stochastic forcing, which arises in the modeling of liquid crystals. In this talk, we focus on the existence of local-in-time regular solutions, the occurrence of finite-time blow-up, and the existence of global martingale weak solutions. Additionally, we explore the small-mass limit, known as the Smoluchowski-Kramers approximation, proving that the solution converges to that of a stochastic quasilinear parabolic equation. This is a joint work with Julien Vovelle.
