Chen, Xueqing; Wang, Qiang A note on hereditary semigroup algebras. (English) Zbl 1083.16019 Nam, Ki-Bong (ed.) et al., Pragmatic algebra. Delhi: SAS International Publications (ISBN 81-88296-02-3/hbk). 181-186 (2006). Summary: We give a new computational proof of when semigroup algebras \(K_0[S^1]\) of non-null Rees matrix semigroups \(S={\mathcal M}^0(1;N,M;P)\) are hereditary.For the entire collection see [Zbl 1078.00017].
