Unstable Blowups
Let (X,L) be a polarised manifold. We show that K-stability and asymptotic Chow stability of the blowup of X along a 0-dimensional cycle are closely related to Chow stability of the cycle itself, for polarizations making the exceptional divisors small. This can be used to give (almost) a converse to the results of Arezzo and Pacard in [1], [2], and to give new examples of Kähler classes with no...
متن کاملFlag Higher Nash Blowups
In his previous paper [5], the author has defined a higher version of the Nash blowup and considered it a possible candidate for the one-step resolution. In this paper, we will introduce another higher version of the Nash blowup and prove that it is compatible with products and smooth morphisms. We will also prove that the product of curves can be desingularized via both versions.
متن کاملHigher Nash Blowups
For each non-negative integer n, we define the n-th Nash blowup of an algebraic variety, and call them all higher Nash blowups. When n = 1, it coincides with the classical Nash blowup. We prove that sufficiently high Nash blowups separate analytic branches. We also determine for a monomial curve in characteristic zero when its higher Nash blowups are smooth.
متن کاملHomology Localization by Hierarchical Blowups
Topological descriptors such as the generators of homology groups are very useful in the analysis of complex data sets. It is often desired to find the smallest such generators to help localize the interesting features. One interpretation of localization utilizes a covering of the underlying space and computes generators contained within these covers. A similar construction was later used to co...
متن کاملSeven short stories on blowups and resolutions
The lectures adress to students and geometers who are not experts in the field, but who need to use blowups occasionally or who just want to have a good comprehension of them. References are scattered in the literature and mostly concentrate on only part of the story. This text is neither complete, but hints at least at the variety of properties, results and techniques which are related to blow...
