H.-J. Schmidt
TL;DR
This paper introduces a new class of inhomogeneous cosmological models derived from the Einstein-de Sitter universe, featuring flat spatial slices and satisfying energy conditions under specific assumptions.
Contribution
It presents a method to generate inhomogeneous models with flat slices from the Einstein-de Sitter universe using a transformation, expanding the set of viable cosmological solutions.
Findings
Models possess flat slices t=const.
Models satisfy certain energy conditions.
Transformation from Einstein-de Sitter universe is feasible.
Abstract
A family of cosmological models is considered which in a certain synchronized system of reference possess flat slices t = const. They are generated from the Einstein-de Sitter universe by a suitable transformation. Under physically reasonable presumptions these transformed models fulfil certain energy conditions.
