As a representation of G, for a dominant weight , hol(L ) is the dual of a non-zero, irreducible … WebNext, we will show how these two new theories are connected by a derived generalization of the Borel—Bott—Weil theorem. Finally, we will discuss how this framework broadens the application range of classical theories and sheds new light on many classical problems, including the study of derived categoriesof singular schemes, and of Hilbert ...
