The $\Box_b$-heat equation on quadric manifolds

In this article, we give an explicit calculation of the partial Fourier transform of the $\Box_b$-heat equation on quadric submanifolds of $M\subset C^n\times C^m$. As a consequence, we can also compute the heat kernel associated to the weighted dbar-equation in $C^n$ when the weight is given by $\exp(-ϕ(z,z)\cdotλ)$ where $ϕ: C^n\times C^n\to C^m$ is a quadratic, sesquilinear form and $λ\in R^m$. Our method involves the representation theory of the Lie group $M$ and the group Fourier transform.
