Let $B=(b_{ij})_{i,j=0}^{n-1}$ be a biresidue matrix. It is holonomic if, for every subset $J\subset\{0,1,\dots,n-1\}$ of odd cardinality, the linear span of the rows of the submat…

Let $\mathsf{X}=\mathbb{P}^{n-1}\times\mathbb{D}^m$ and let $\pi(\varepsilon)=\sum_{k=0}^{\infty}\varepsilon^k\pi_k$ be the formal Poisson deformation whose existence is asserted f…

Partial compactification conjecture. The variety $\overline{X}_{\tau}$ is the desired partial compactification of $X_{\tau}$. This construction is intended to provide a systematic…
