Query: Equivalence of two solutions of physical massive gravity   We study some aspects of linearized gravity as gauge theory, with massive
deformation. Recently it has been shown that there are two distinct solutions,
which represent physical massive gravity. The purpose of the present work is to
show that these two seemingly discrete solutions are equivalent at the level of
generating functional. The significance of this simple work lies in the fact
that one solution represent physical massive gravity at Fierz-Pauli (FP) point
and other outside the FP point.
