GW/PT-correspondence for CY -fold-II: Virtual Classes
Ivan Karpov
Let be a complex manifold and $f:\bX\to B$ a derived \textit{complex-analytic} (not necessarily \textit{algebraic}) space with an oriented relative -shifted symplectic st…
Conditional expectile-based value-at-risk: Semiparametric estimation and inference
Yuhan Ma, Heng Peng, Feipeng Zhang
Conditional expectile-based value-at-risk (EVaR) has attracted increasing attention in financial risk management owing to its desirable theoretical properties. However, existing es…
The quantum Hikita conjecture via quasimaps
Hunter Dinkins, Ivan Karpov, Vasily Krylov
We propose a refinement of the quantum Hikita conjecture of Kamnitzer, McBreen, and Proudfoot that bridges the representation theory of Coulomb branches with the enumerative geomet…
On the Feyzbakhsh-Thomas programme for Fano -folds
Ivan Karpov, Miguel Moreira
Let be a Fano -fold with even canonical class which satisfies the generalized Bogomolov-Gieseker inequality, such as . We express Donaldson-Thomas invariants co…
Rationality and symmetry of stable pairs generating series of Fano 3-folds
Ivan Karpov, Miguel Moreira
The generating series of descendent invariants of stable pairs on 3-folds is conjectured to be rational and to satisfy a symmetry. We prove this conjectur…
