$W(0,b)$ algebra and the dual theory of 3D asymptotically flat higher spin gravity

Nabamita Banerjee, Arindam Bhattacharjee, Surajit Biswas +2

BMS algebra in three spacetime dimensions can be deformed into a two parameter family of algebra known as $W(a,b)$ algebra. For $a=0$, we show that other than $W(0,-1)$, no other $…
