We show that the derived category of a curve is embedded into the derived category of the moduli space of vector bundles on the curve of coprime rank and degree. We also generalize the semiorthogonal decomposition constructed by Narasimhan and Belman

We prove that the only rational homogeneous varieties with Picard number 1 of the exceptional algebraic groups admitting irreducible equivariant Ulrich vector bundles are the Cayley plane $E_6/P_1$ and the $E_7$-adjoint variety $E_7/P_1$. From this r

In this paper we study effective, nef and semiample cones of minimal surfaces of general type with p g = 0 . We provide examples of minimal surfaces of general type with p g = 0 and 2 ≤ K 2 ≤ 9 which are Mori dream spaces. On these examples we al

Let $S=(C \times D)/G$ be a surface isogenous to a higher product of unmixed type with $p_g=q=0$, $G=(\mathbb{Z}/2)^3$ or $(\mathbb{Z}/2)^4$. We construct exceptional sequences of maximal length and quasiphantom categories on $S$.

In this paper, we study effective, nef and semiample cones of surfaces isogenous to a product of mixed type with $p_g=0$. In particular, we prove that all reducible fake quadrics are Mori dream surfaces.

Let C be an irreducible smooth complex projective curve of genus g ¿ 2 and Cd its d-fold symmetric product. In this paper, we study the question of semi-orthogonal decompositions of the derived category of Cd. This entails investigations of the cano

Let S = ( C × D ) / G be a surface isogenous to a higher product of unmixed type with p g = q = 0 , G = ( Z / 3 ) 2 . We construct exceptional sequences of line bundles of maximal length on S. As a consequence we find new examples of quasiphantom ca

In this paper, we investigate the existence of Ulrich bundles on a smooth complete intersection of two $4$-dimensional quadrics in $\mathbb P^5$ by two completely different methods. First, we find good ACM curves and use Serre correspondence in order
