Two-Dimensional Torus Action on the Quadric Threefold and GW-DT-GV Correspondence

Kiryong Chung, Sanghyeon Lee

We compute Gromov--Witten (GW) and Donaldson-Thomas (DT) invariants (including descendant invariants) for local CY $4$ -folds over a smooth quadric threefold $Q$ , up to degree $4$ .…

Infinitesimal automorphisms and obstruction theory on the moduli of $L$ -valued $G$ -Higgs bundles

Sanghyeon Lee, Sang-Bum Yoo

For an arbitrary reductive group $G$ , we compute the infinitesimal automorphisms of $L$ -valued principal $G$ -Higgs bundles over a compact Kähler manifold $X$ , extending known resul…
