Exotic t-structures and actions of quantum affine algebras
Exotic t-structures and actions of quantum affine algebras
We explain how quantum affine algebra actions can be used to systematically construct "exotic" t-structures. The main idea, roughly speaking, is to take advantage of the two different descriptions of quantum affine algebras, the Drinfeld–Jimbo and the Kac–Moody realizations. Our main application is to obtain exotic t-structures on certain convolution …
