Instantons on flat space: Explicit constructions
Jason D. Lotay, Thomas Bruun Madsen
In this note, we revisit some well-known examples of instantons on flat space that were originally discovered in the physics literature. In particular, we explain how the basic ins…

Toric geometry of Spin(7)-manifolds
Thomas Bruun Madsen, Andrew Swann
We study -manifolds with an effective multi-Hamiltonian action of a four-torus. On an open dense set, we provide a Gibbons-Hawking type ansatz that describes such…

Toric geometry of -manifolds
Thomas Bruun Madsen, Andrew Swann
We consider -manifolds with an effective torus action that is multi-Hamiltonian for one or more of the defining forms. The case of -actions is found to be distinguished.…
