Exercise 4.The heat kernel on $latex \mathbb{S}^1$ is given by $latex p(t,y) =\frac{1}{2\pi}\sum_{m \in \mathbb{Z}} e^{-m^2 t} e^{im y} =\frac{1}{\sqrt{4\pi t}} \sum_{k \in \mathbb{Z}} e^{-\frac{(y...

| | Let $latex x\in C^{1-var} ([0,T], \mathbb{R}^d)$ and let $latex V : \mathbb{R}^e \to \mathbb{R}^{e\times d} $ be a Lipschitz continuous map. In order to analyse the solution of the differential equation, $latex y(t)=y_0+\int_0^t V(y(s)) dx(s),$ and make the geometry enter into the scene, it is convenient to see $latex V$ as a collection of vector...
