Green index and finiteness conditions for semigroups [PDF]

open access: yes, 2008
Let S be a semigroup and let T be a subsemigroup of S. Then T acts on S by left and by right multiplication. If the complement S \ T has finitely many strong orbits by both these actions we say that T has finite Green index in S.

The structure of index sets and reduced indexed grammars [PDF]

open access: yesRAIRO - Theoretical Informatics and Applications, 1990
Summary: The set of index words attached to a variable in derivations of indexed grammars is investigated. Using the regularity of these sets it is possible to transform an indexed grammar in a reduced form and to describe the structure of left sentential forms of an indexed grammar.
