Weighted diagonal-harmonics isomorphism conjecture. The spaces $\mathcal D_n^{\mathbf a}$ and $\mathcal D_n$ are isomorphic as graded vector spaces. The source presents this as a r…

Let $\mathcal D_n^{\mathbf a}$ be the common polynomial zero space in $\mathbb C[\mathbf{x},\mathbf{y}]$ of the operators … for all $k,j\in\mathbb N$ with $k+j>0$. Assume that…
