Graphene shows unusual low-energy electronic excitations described in terms of Dirac fermions. The Fractional quantum Hall effect in a bilayer graphene in different Landau levels within the supersymmetric formalism has been Studied. The quantized Hall conductivity is found to be sigma(xy) = +/- (n+1)v e(2)/h, where n = 0, 1, 2, 3 ...
