<strong>Supersonic</strong> Inflation<br />

subsonic flow: KK = vv ss tt ii / DD 00<br />

supersonic flow:<br />

KK(ρρ CC / ρρ 00) ) = vv ss tt ii / DD 00 - Greene<br />

KK(uu <strong>11</strong> / uu 22) ) = vv ss tt ii / DD 00<br />

these these are virtually equivalent since for continuity<br />

uu 1 1 ρρ <strong>11</strong> = uu 2 2 ρρ 22 across a shock wave
