Lagrangian classes in K-theory
Dongwook Choa, Jeongseok Oh
For a -shifted Lagrangian in a critical locus, we construct a homomorphism from the -group of matrix factorisations of the critical locus to the -group of the Lagrangia…
A Hopf index for isotropic sections of orthogonal bundles
Martijn Kool, Jeongseok Oh, Jørgen Vold Rennemo +1
The Hopf index equates the multiplicity of a zero of a section of a vector bundle with a winding number. We give eight analogues for isotropic sections of bundles with quadratic fo…
Gromov-Witten invariants in family and quantum cohomology
Indranil Biswas, Nilkantha Das, Jeongseok Oh +1
A moduli space of stable maps to the fibers of a fiber bundle is constructed. The new moduli space is a family version of the classical moduli space of stable maps to a non-singula…
Quantum Lefschetz without curves
Jeongseok Oh, Richard P. Thomas
Given one quasi-smooth derived space cut out of another by a section of a 2-term complex of bundles, we give two formulae for its virtual cycle. They are modelled on the the -fi…
Mirror theorem for elliptic quasimap invariants of local Calabi-Yau varieties
Hyenho Lho, Jeongseok Oh
The elliptic quasimap potential function is explicitly calculated for Calabi-Yau complete intersections in projective spaces by Kim and Lho. We extend this result to local Calabi-Y…
