Differentiability and Convexity of the Solution Maps for Fully Non-linear Parabolic HJB Equations

We study the dependence on the terminal condition of solutions to a fully nonlinear parabolic Hamilton--Jacobi--Bellman (HJB) equation, when the terminal condition varies along a finite-dimensional family. This problem is motivated by a dual formulation of semimartingale optimal transport. The equation is posed as a te...
