Algebraization theorems for coherent sheaves on stacks
Abstract/Contents
- Abstract
- Given a moduli problem, two important questions one can ask are the following: Is there an algebraic stack representing the moduli problem? If so, does it have a coarse space? A necessary step to answering these questions in the post-GIT era is to prove an algebraization result akin to formal GAGA for proper schemes. In this dissertation, we will present two such results. The first result (Chapter 2) is Grothendieck's existence theorem for relatively perfect complexes on an algebraic stack. This generalizes work of Lieblich in the setting of algebraic spaces. The second result (Chapter 3) is coherent completeness of BG (with G a split reductive group) and [\SL_d \backslash \mathbf{A}^d]. The results of this chapter are joint work with Jack Hall and are an important step to extending the \'{e}tale slice theorem of Alper-Hall-Rydh to positive characteristic. Finally, in future work with Jack Hall and Jarod Alper, we prove that an arbitrary [G \backslash \spec A] with G reductive is coherently complete
