An alternative to the standard cold dark matter model has been recently
proposed in which a significant fraction of the energy density of the universe
is due to a dynamical scalar field (Q) whose effective equation-of-state
differs from that of matter, radiation or cosmological constant (Λ). In
this paper, we determine how the Q-component modifies the primordial inflation
gravitational wave (tensor metric) contribution to the cosmic microwave
background anisotropy and, thereby, one of the key tests of inflation.Comment: 15 pages, 14 figures, revtex, submitted to Phys. Rev.
