Let R := R 2 (p) = C[t ±1 , u : u 2 = t(t − α 1 ) · · · (t − α 2n )] be the coordinate ring of a nonsingular hyperelliptic curve and let g ⊗ R be the corresponding current Lie algebra. Here g is a finite dimensional simple Lie algebra defined over C andIn earlier work, Cox and Im gave a generator and relations description of the universal central extension of g ⊗ R in terms of certain families of polynomials P k,i and Q k,i and they described how the center Ω R /dR of this universal central extension decomposes into a direct sum of irreducible representations when the automorphism group was the cyclic group C 2k or the dihedral group D 2k . We give examples of 2n-tuples (α 1 , . . . , α 2n ), which are the automorphism groups G n = Dic n , U n ∼ = D n (n odd), or U n (n even) of the hyperelliptic curvesgiven in [CGLZ17]. In the work below, we describe this decomposition when the automorphism group is U n = D n , where n is odd.
