Query: On Finite-Index Indexed Grammars and Their Restrictions   The family, L(INDLIN), of languages generated by linear indexed grammars has
been studied in the literature. It is known that the Parikh image of every
language in L(INDLIN) is semi-linear. However, there are bounded semi linear
languages that are not in L(INDLIN). Here, we look at larger families of
(restricted) indexed languages and study their properties, their relationships,
and their decidability properties.
