I.M. Khalatnikov, A.Yu. Kamenshchik
TL;DR
This paper presents a new exact solution to Einstein's equations for a Bianchi-I universe that includes dust, stiff matter, and a cosmological constant, extending the classic Heckmann-Schucking solution.
Contribution
It generalizes the Heckmann-Schucking solution to include additional matter components and a cosmological constant, broadening the scope of exact cosmological models.
Findings
Derived a new exact solution for Bianchi-I universe with multiple matter types.
Extended the classic Heckmann-Schucking solution to more general conditions.
Provides insights into anisotropic universe models with complex matter content.
Abstract
An exact solution of the Einstein equations for a Bianchi -I universe in the presence of dust, stiff matter and cosmological constant, generalising the well-known Heckmann-Schucking solution is presented. PACS: 04.20-q; 04.20.Dw Keywords: Exact cosmological solutions
