Query: Boundary conditions of the RGE flow in the noncommutative geometry
  approach to particle physics and cosmology   We investigate the effect of varying boundary conditions on the
renormalization group flow in a recently developed noncommutative geometry
model of particle physics and cosmology. We first show that there is a
sensitive dependence on the initial conditions at unification, so that, varying
a parameter even slightly can be shown to have drastic effects on the running
of the model parameters. We compare the running in the case of the default and
the maximal mixing conditions at unification. We then exhibit explicitly a
particular choice of initial conditions at the unification scale, in the form
of modified maximal mixing conditions, which have the property that they
satisfy all the geometric constraints imposed by the noncommutative geometry of
the model at unification, and at the same time, after running them down to
lower energies with the renormalization group flow, they still agree in order
of magnitude with the predictions at the electroweak scale.
