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.
For the entire collection see [Zbl 1317.00020].
