The GL(4 R) Yang-Mills Theory of Gravity Predicts An Inflationary
Scenario For The Evolution of The Primordial Universe    [PDF]

Yi Yang, Wai Bong Yeung

We show that the GL(4 R) gauge theory of gravity will admit an exponentially expanding solution for the primordial evolution of the Universe. This inflationary phase of the Universe is driven by a rapidly changing GL(4 R) gauge field configuration. No cosmological constant and no rolling scalar field is required. This inflationary expansion will then be shown to slow down to a much slower expansion rate during the late time evolution of the Universe.
