Note on Harmonic Exponential Families on Homogeneous Spaces
摘要
In [6], we proposed a method to construct a G-invariant exponential family on a homogeneous space G/H by using a representation of G. In this paper, we prove that for any G-invariant exponential family \(\mathcal {P}\) on G/H, we can construct a family \(\mathcal {P}_0\) by the method which satisfies \(\mathcal {P}\subset \mathcal {P}_0\) .
