Finite-generation conjecture for quasimap potentials of K3 fibrations

At least 6 years old · documented by

Let X→BX\rightarrow B be a K3 fibration and, for γ∈H2(B,Z)\gamma\in H_2(B,\mathbb Z), let Fg,γSQ\mathcal{F}^{\mathsf{SQ}}_{g,\gamma} be the associated quasimap series. Define

L(q)=(1−44q)−1/4,A1′(q)=q∂∂qI1K3(q),L(q)=(1-4^4q)^{-1/4},\qquad A_1'(q)=q\frac{\partial}{\partial q}I_1^{K3}(q),

and

X(q)=q∂∂qA1′(q)1+A1′(q),QKF=C[L±4,A1′,X].X(q)=\frac{q\frac{\partial}{\partial q}A_1'(q)}{1+A_1'(q)},\qquad \mathsf{QKF}=\mathbb C[L^{\pm4},A_1',X].

K3-fibration finite-generation conjecture. For γ∈H2(B,Z)\gamma\in H_2(B,\mathbb Z),

Fg,γSQ∈QKF.\mathcal{F}^{\mathsf{SQ}}_{g,\gamma}\in\mathsf{QKF}.

This is one of the proposed finite-generation properties for K3-fibration quasimap potentials, intended to yield consequences for Gromov–Witten potentials through wall crossing; the source provides no resolution status.
