New moduli spaces of one-dimensional sheaves on $\mathbb{P}^3$

Abstract

We define a one-dimensional family of "Euler" stability conditions on Pn\mathbb{P}^n which are conjectured to converge to Gieseker stability for coherent sheaves. Here, we focus on P3{\mathbb P}^3, first identifying Euler stability conditions with double-tilt stability conditions, and then we consider moduli of one-dimensional sheaves, proving some asymptotic results, boundedness for walls, and then explicitly computing walls and wall-crossings for sheaves supported on rational curves of degrees 33 and 44.
