The goodness of {S,a}-EOL forms is decidable

TL;DR: It is proved that given an EOL form F with one nonterminal and one terminal (a so-called {S, a}-EOL form) it is decidable whether or not F is good.

EOL forms and finite substitutions of ol forms

TL;DR: EOL language families are related to OL language families using finite substitutions, homomorphism and codings to show that each sub-context free EPOL language family is sublinear.

On Good EOL Forms

TL;DR: The notion of a good EOL form is introduced as an important generalization of the notion of complete and very complete EOL forms and Transformations preserving the property good are obtained.

Synchronized E0L forms

TL;DR: The syntax analysis of synchro-E0L form families is lead into the study of ambiguity in E0L systems, and it is shown that there are languages which are n-CF-ambiguous, for arbitrarily large values of n ⩾ 1, but which are E 0L-unambiguous.

Increasing the similarity of EOL form interpretations

TL;DR: This work claims that by using the notion of X -uniformity and cc -interpretation this drawback of ordinary interpretations of EOL forms can be overcome.

On pure, terminal invariant and nonterminal invariant interpretations of EOL forms

TL;DR: Certain results are proved which show that synchronized EOL forms have a natural place in the theory of E OL forms (independently of their role as the normal form for EOL systems on language level).

Synchronized, desynchronized and coordinated E0L systems

TL;DR: This paper presents a systematic study of the phenomenon of synchronization in E0L systems by abstracting various essential features of derivations in those systems the notions of a coordinated and a desynchronized E0l system are formulated and properties of the classes of languages they generate studied.
