  Comparison of theobservedanisotropy with that predicted iadiabaticDM models
suggest that much of thserved signal may be due to long wavelenh gravitational
waves. In inflationary models this requires the generation of tensor
fluctuations to be at least comparable to scalar density fltuations. This i is
feasible, but depends sensitively on the inflaton potential. Alternatively,
isocurvature quantum fluctuations in an axion-like field could produce a
quadrupole anisotropy proportional to the gravitational wave anisotropy,k
independent of the inflaton potential. These could also produce large scale
structure with more power on larger scales than their adiabatic counterparts.
