(One of the claims in the paper is wrong. Namely, Theorem 2.1 claims that the monoid $TB_n$ of all triangular Boolean matrices is inherently nonfinitely based if and only if $n>3$. In fact, the monoid $TB_3$ is inherently nonfinitely based as well; this has been shown by Li and Luo (cf. Li, J.R., Luo, Y.F.: On the finite basis problem for the monoids of triangular boolean matrices. Algebra Universalis (2011) 65, 353-362). Li and Luo have also checked that the monoid $TB_2$ is finitely based.)
