###Analysis on homogeneous cones and beyond
The set of positive definite real symmetric matrices is a typical example of homogeneous cone. Because of its rich symmetry, a lot of beautiful integral formulas hold over the homogeneous cone. And recently, statisticians find that some of the formulas are valid even for non-homogeneous cones.
