Abstract

We propose a slightly modified definition for the Fourier–Mukai transform (on abelian varieties) that makes it much easier to remember various formulas. As an application, we give short proofs for two important theorems: the characterization of GV-sheaves in terms of vanishing, due to Hacon; and fact that M-regularity implies (continuous) global generation, due to Pareschi and Popa.

Keywords

Fourier–Mukai transform, abelian variety, GV-sheaf, $m$-regularity
