Stasinski, Alexander (2021) 'Representations of SL over finite local rings of length two.', Journal of algebra., 566 . pp. 119-135.


Let Fqbe a finite field of characteristic pand let W2(Fq)be the ring of Witt vectors of length two over Fq. We prove that for any integer nsuch that pdivides n, the groups SLn(Fq[t]/t2)and SLn(W2(Fq)) have the same number of irreducible representations of dimension d, for each d
