Summary: Let \(X\) be a four-manifold with boundary three-manifold \(M\). We shall describe (i) a pre-symplectic structure on the space \(\mathcal{A}(X)\) of connections on the bundle \(X \times\mathrm{SU}(n)\) that comes from the canonical symplectic structure on the cotangent space \(T ^\ast \mathcal{A}(X)\). By the boundary restriction of this pre-symplectic structure we obtain a pre-symplectic structure on the space \(\mathcal{A}^\flat_0(M)\) of flat connections on \(M \times \mathrm{SU}(n)\) that have null charge.
