7.1 Equations, polarized T3-Gowdy

In the case of polarized Gowdy, Q = 0, so that Equations (16View Equation) – (19View Equation) reduce to
P − e−2τP = 0, (29 ) ττ šœƒšœƒ λτ = P 2τ + e−2τPšœƒ2, (30 ) λ = 2P P . (31 ) šœƒ šœƒ τ
As an aside, it is of interest to note that the set Q = 0 coincides with the image of a geodesic in hyperbolic space (ā„2, gR). This system of equations should be compared with (11a) – (11d) of [50Jump To The Next Citation Point] (note, however, that the variables of [50Jump To The Next Citation Point] are somewhat different).
