Abstract: We classify (m + n)D warped product spaces (M¯,g¯) satisfying Einstein’s equation G¯=−Λ¯g¯. We show that the warping function f can determine not only the cosmological constant Λ¯ but also the cosmological constant Λ appearing… read more here.

Abstract: ABSTRACT In this paper, we consider the Cauchy problem for the spatially inhomogeneous relativistic Boltzmann equation where the collision kernel is generated by Israel particle. Unique global (in time) classical solution is obtained in a… read more here.
