Towards dimension theory for spectral semi- orthogonal decompositions M. L. Kontsevich Institut des Hautes Études Scientifiques |

Аннотация: It is expected that the derived category of coherent sheaves on a smooth projective variety has a canonical semiorthogonal decomposition governed by the generic spectrum of quantum multiplication deformed by algebraic classes. I present a hypothetical formula for the Serre dimension of elementary pieces for complete interesections in projective spaces, and sketch applications to the rationality questions.
