Stability condition on Calabi-Yau threefold of complete intersection of quadratic and quartic hypersurfaces

Abstract

In this paper, we prove a Clifford type inequality for the curve $X_{2,2,2,4}$, which is the intersection of a quartic and three general quadratics in $\mathbb{P}^5$. We thus prove a stronger Bogomolov-Gieseker inequality for characters of stable vector bundles and stable objects on $X_{2,4}$. Applying the scheme proposed by Bayer, Bertram, Macr\`i, Stellari and Toda, we can construct an open subset of Bridgeland stability conditions on $X_{2,4}$.
