Existence and Smoothing for a Nondivergence-Form Degenerate Diffusion from Plasma-Wave Theory
William Porteous, Irene M. Gamba, Kun Huang
We prove existence, positive-time smoothing, and physical admissibility of weak solutions to the degenerate parabolic Cauchy-Dirichlet problem $\partial_t u = ρ_λ(x) u \partial_x^2…

Diffusion-Based Posterior Sampling: A Feynman-Kac Analysis of Bias and Stability
Matias G. Delgadino, Sebastien Motsch, Advait Parulekar +2
Diffusion-based posterior samplers use pretrained diffusion priors to sample from measurement- or reward-conditioned posteriors, and are widely used for inverse problems. Yet their…
