✦ Synopsis
The purpose of this note is to define tri-momentum maps for certain manifolds with an Sp(1) n -action. We exhibit many interesting examples of such spaces using quaternions. We show how these maps can be used to reduce such manifolds to ones with fewer symmetries. The images of such maps for quaternionic flag manifolds, which are defined using the Dieudonné determinant, resemble the polytopes from the complex case.
