For several classes of models (continuous space polymer models in

positive and zero temperature, HJB equations in dynamic environments),

we show that the shape function (also known as the effective

Lagrangian in the homogenization context) is differentiable and give a

formula for its gradient. Joint work with Douglas Dow.
