Charlotte Kirchhoff-Lukat, Marco Zambon

TL;DR
This paper studies the moduli space of spacefilling branes on symplectic 4-manifolds, showing smoothness and dimension for certain compact cases using Torelli theorems.
Contribution
It establishes the smoothness and computes the dimension of the moduli space of spacefilling branes on holomorphic symplectic compact Kähler 4-manifolds.
Findings
Moduli space is smooth for holomorphic symplectic compact Kähler 4-manifolds.
The dimension of the moduli space is explicitly determined.
The proof uses the local Torelli theorem for K3 surfaces and tori.
Abstract
On a symplectic manifold , a spacefilling brane structure is a closed 2-form which determines a complex structure, with respect to which is holomorphic symplectic. For holomorphic symplectic compact K\"ahler 4-manifolds, we show that the moduli space of spacefilling branes is smooth, and determine its dimension. The proof relies on the local Torelli theorem for K3 surfaces and tori.
