Mewomo, O. T.; Mebawondu, A. A.; Adiele, U. O.; Olanipekun, P. O. On character pseudo-amenable semigroup algebras. (English) Zbl 1396.46039 Proc. Jangjeon Math. Soc. 20, No. 4, 583-593 (2017). The authors study character amenability and character pseudo-amenability of Banach algebras. In particular, they prove that, for a Brandt semigroup \(S\) over the group \(G\), if \(\ell ^1(S)\) is left or right character pseudo-amenable, then \(G\) is an amenable group.
