Natural dualities for some subvarieties of DMS (Q1382735)

This paper is concerned with natural dualities for subvarieties of double MS-algebras. The main result and consequences are summarised, but the paper suffers from rather unacceptable phrases such as `We bypass the explicit listing \(\dots\) because there are many and they can be easily obtained by computer' and `\(\dots\) the free algebras on \(n\) generators for each subvariety of \({\mathbf {DMS}}\) can also be described. We omit this to avoid notational complications.' There is no discussion of the validity of the computer output.
