Orlov's equivalence and maximal Cohen‐Macaulay modules over the cone of an elliptic curve

Abstract: We describe a method for doing computations with Orlov's equivalence between the bounded derived category of certain hypersurfaces and the stable category of graded matrix factorisations of the polynomials describing these hypersurfaces. In the case of a smooth elliptic curve over an algebraically closed field we describe the indecomposable graded matrix factorisations of rank one. Since every indecomposable Maximal Cohen-Macaulay module over the completion of a smooth cubic curve is gradable, we obtain explic… Show more

“…Classification of rank 1 MCM modules over the general Hesse cubic x 3 0 + x 3 1 + x 3 2 − 3ψx 0 x 1 x 2 = 0 follows immediately from our results, where the only non-trivial case is given by Moore's matrices. Analogous classification for rank 1 MCM modules over Weierstrass cubics y 2 z − x 3 − axz − bz 3 = 0 here obtained more recently in [18].…”

“…Studying linear determinantal representations of smooth plane cubics is a classical topic in linear algebra and algebraic geometry ( [Vin89], [Dol12]). Recently, they appear in the study of the derived category of smooth plane cubics ( [Gal14]) and the theory of space-time codes ( [DG08]). They have been studied from arithmetic viewpoints ( [FN14], [II16a], [Ish15]).…”
