Witten’s top Chern class via cosection localization

Inventiones Mathematicae, 2013
For a Landau–Ginzburg space $$([\mathbb {C}^n/G],W)$$([Cn/G],W), we construct Witten’s top Chern class as an algebraic cycle using cosection localized virtual cycles in the case where all sectors are narrow, verify all axioms of this class, and derive an

Second Chern class of Fano manifolds and anti-canonical geometry

Mathematische Annalen, 2017
Let X be a Fano manifold of Picard number one. We establish a lower bound for the second Chern class of X in terms of its index and degree. As an application, if Y is a n-dimensional Fano manifold with $$-K_Y=(n-3)H$$-KY=(n-3)H for some ample divisor H ...
