Semiorthogonal decomposition

In mathematics, a semiorthogonal decomposition is a way to divide a triangulated category into simpler pieces. One way to produce a semiorthogonal decomposition is from an exceptional collection, a special sequence of objects in a triangulated category. For an algebraic variety X, it has been fruitful to study semiorthogonal decompositions of the bounded derived category of coherent sheaves, . (Wikipedia).

Marcello Bernardara: Semiorthogonal decompositions and birational geometry of geometrically rational

Abstract:This is a joint work in progress with A. Auel. Let S be a geometrically rational del Pezzo surface over a field k. In this talk, I will show how the k-rationality of S is equivalent to the existence of some semiorthogonal decompositions of its derived category. In particular, the

Embedding the derived category of a curve into a Fano variety - Alexander Kuznetsov

Alexander Kuznetsov Steklov Mathematical Institute, Moscow April 14, 2015 According to the conjecture of Bondal, the derived category of coherent sheaves on any smooth projective variety can be embedded as a semiorthogonal component into the derived category of a Fano variety of higher dim

What are Graph Decompositions? | Graph Decomposition, Graph Theory

What is a graph decomposition? Graph decompositions are studied quite extensively by many in graph theory, and we’ll go over what they are, and plenty of examples in today’s video graph theory lesson! We can decompose a graph into subgraphs, but in order for this to be a decomposition the
