The reflexive closure of the adjointable operators
Given a Hilbert module E over a C*-algebra A, we show that the collection of
all bounded A-module operators acting on E forms the reflexive closure for the
algebra of the adjointable operators. We also make an observation regarding the
representation theory of the left centralizer algebra of a C*-algebra and use
it to give an intuitive proof of a related result of H. LinComment: The paper will appear in the Illinois J. Mat
Trailing Edge Unification via an Intermediate Pati-Salam Group
We demonstrate to two-loop order that an intermediate symmetrically embedded
Pati-Salam level of symmetry is all that
is necessary to accommodate empirical values of
and within a grand unification context but with a high
(10^{14} GeV) intermediate mass scale and with a concomitant higher GUT scale.Comment: 7 pages, 4 embedded eps figur
