摘要

Qregularity is a notion of Castelnuovo-Mumford regularity for quadric hypersurfaces introduced in 3. Here, we give bounds for the Qregularity of bundles arising from a quasi-linear monad. Then, we study the Qregularity of odd and even instantons bundles and we discuss sharpness. These results are the analogous of those on projective spaces for Castelnuovo-Mumford regularity.
