Abstract
G. Pareschi and M. Popa give criterions for global generations and surjectivity of multiplication maps of global sections of coherent sheaves on abelian varieties in the theory of M-regularity. In this paper, we generalize some of their criterions via the M-regularity of -twisted sheaves. As an application, we show that the M-regularity of a suitable -twisted sheaf implies property and jet-ampleness for ample line bundles on abelian varieties.
