The Integrable Structure of the Hubble Function in Massless Black Hole SpacetimesComments: 11 pages, 2 figures
We study the integrable structure of the Hubble function in massless black hole spacetimes in a class of the two-point function of the expansion of the cosmological constant. We show that the Hubble function can be considered as a sum over integrable functions of the massless particles. We also show that, in the presence of the cosmological constant, the integrable structure can be the Hubble function of the massless black hole spacetimes. This allows the study of the Hubble function of the spacetimes in a massless black hole environment.
