| Abstract： |
This paper constructs a finite Lie conformal superalgebra R associated to
the N = 1 Bondi-Metzner-Sachs (BMS for short) superalgebra. The authors completely
determine conformal derivations, the automorphism group, and the second cohomology
with coefficients in trivial module. They also classify free conformal modules of rank
(1 + 1) and finite irreducible conformal modules over R. |
