Enhanced asymptotic $BMS_3$ algebra of the flat spacetime solutions of generalized minimal massive gravity

Understand

We apply the new fall of conditions presented in the paper \cite{10} on asymptotically flat spacetime solutions of Chern-Simons-like theories of gravity.

• We show that the considered fall of conditions asymptotically solve equations of motion of generalized minimal massive gravity.
• We demonstrate that there exist two type of solutions, one of those is trivial and the others are non-trivial.
• By looking at non-trivial solutions, for asymptotically flat spacetimes in the generalized minimal massive gravity, in contrast to Einstein gravity, cosmological parameter can be non-zero.
