Gauge symmetry and uniqueness in inverse problems for the JMGT equation
Nonlinear acoustic coefficient β is uniquely determined from the all-boundary measurement map for the JMGT equation; linear coefficients α, q and source F are recovered up to gauge symmetry via linearization and geometric optics.
