Sasakian Geometry, Holonomy, and Supersymmetry

open access: yes, 2007
In this expository article we discuss the relations between Sasakian geometry, reduced holonomy and supersymmetry. It is well known that the Riemannian manifolds other than the round spheres that admit real Killing spinors are precisely Sasaki-Einstein ...

Riemannian Gaussian distributions on the space of positive-definite quaternion matrices

open access: yes, 2017
Recently, Riemannian Gaussian distributions were defined on spaces of positive-definite real and complex matrices. The present paper extends this definition to the space of positive-definite quaternion matrices.
