Compactified moduli spaces of rational curves in projective homogeneous varieties
Kiryong Chung, Jaehyun Hong, Young-Hoon Kiem
The space of smooth rational curves of degree in a projective variety has compactifications by taking closures in the Hilbert scheme, the moduli space of stable sheaves or…

Localizing Virtual Cycles by Cosections
Young-Hoon Kiem, Jun Li
We show that a cosection of the obstruction sheaf of a perfect obstruction theory localizes the virtual cycle to the non-surjective locus of the cosection. We give algebraic constr…

Moduli spaces of weighted pointed stable rational curves via GIT
Young-Hoon Kiem, Han-Bom Moon
We construct the Mumford-Knudsen space of n pointed stable rational curves by a sequence of explicit blow-ups from the GIT quotient (P^1)^n//SL(2) with respect to the symmetric lin…
