Collisions of fat points and applications to interpolation theory. (arXiv:1803.02746v1 [math.AG])

来源于:arXiv
We address the problem to determine the limit of the collision of fat points in $\mathbb{P}^n. We give a description of the limit scheme in many cases, in particular in low dimension and multiplicities. The problem turns out to be closely related with interpolation theory, and as an application we exploit collisions to prove some new cases of Laface-Ugaglia Conjecture. 查看全文>>
