Description
| - A language $L\subseteq A^*$ is literally idempotent in case that $ua^2v\in L$ if and only if $uav\in L$, for each $u,v\in A^*$, $a\in A$. Such classes result naturally by taking all literally idempotent languages in a classical (positive) variety or by considering a certain closure operator on classes of languages. We initiate their systematic study. Various classes of such languages can be characterized using syntactic methods. A starting example is the class of all finite unions of $B^*_1 B^*_2\dots B^*_k$ where $B_1,\dots,B_k$ are subsets of a given alphabet $A$.
