dc.description.abstract	The long-wavelength hydrodynamics of the Renn-Lubensky twist grain boundary phase with grain boundary angle 2πα, α irrational, is studied. We find three propagating sound modes, with two of the three sound speeds vanishing for propagation orthogonal to the grains, and one vanishing for propagation parallel to the grains as well. In addition, we find that the viscosities η1, η2, η4, and η5 diverge like 1/‖ω‖ as frequency ω→0, with the divergent parts Δηi satisfying Δη1Δη4=(Δη5)2, exactly. Our results should also apply to the predicted decoupled lamellar phase.	en
