  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.
