covariance of quadratic form in general

51 Views Asked by At

Let $\mathbf{w}\sim \mathcal{N}(\mathbf{0}, \mathbf{\Sigma})$, and $\mathbf{A, B}$ are symmetric matrices, then it is known that

$ \operatorname{Cov}\left[\mathbf{w^TAw, w^TBw}\right]=2\operatorname{Tr}[\mathbf{A\Sigma B\Sigma}].$

The problem is to compute

$\operatorname{Cov}\left[\mathbf{w^TAw, v^TBv}\right]$, where $\mathbf{w, v}\sim \mathcal{N}(\mathbf{0}, \mathbf{\Sigma})$, and $\mathbf{A, B}$ are symmetric matrices.

Any leads would be appreciated.
