DESCRIPTION:Speaker: Qiuyu Ren\n\nTitle: Lee filtration structure of torus
links\, adjunction inequality\, and applications\n\nAbstract: We state ou
r recent result determining the quantum filtration structure of the Lee hom
ology of torus links. This implies a relative adjunctiontype inequality for
s-invariants of two links related by a link cobordism in kCP2\, originally
conjectured by Manolescu-Marengon-Sarkar-Willis. As two applications of th
is inequality\, we show the existence of knots with arbitrarily large CP2 g
enus\, and we sketch a potential approach to produce and detect exotic kCP2
’s.
