# On the equivalence of linear conjunctive grammars and trellis automata

@article{Okhotin2004OnTE, title={On the equivalence of linear conjunctive grammars and trellis automata}, author={Alexander Okhotin}, journal={RAIRO Theor. Informatics Appl.}, year={2004}, volume={38}, pages={69-88} }

This paper establishes computational equivalence of two seemingly unrelated concepts: linear conjunctive grammars and trellis automata. Trellis automata, also studied under the name of one-way real-time cellular automata, have been known since early 1980s as a purely abstract model of parallel computers, while linear conjunctive grammars, introduced a few years ago, are linear context-free grammars extended with an explicit intersection operation. Their equivalence implies the equivalence of…

Comparing Linear Conjunctive Languages to Subfamilies of the Context-Free Languages

- Computer ScienceSOFSEM
- 2011

This paper investigates subclasses of the context-free languages for possible containment in this class and shows that every visibly pushdown automaton can be simulated by a one-way real-time cellular automaton, but already for LL(1) context- free languages and for one-counter DPDAs no simulation is possible.

Boolean Grammars

- Computer ScienceDevelopments in Language Theory
- 2003

A new class of formal grammars, which allow the use of all set-theoretic operations as an integral part of the formalism of rules, are introduced, which allows to conjecture the practical applicability of the new concept.

Conjunctive Grammars over a Unary Alphabet: Undecidability and Unbounded Growth

- Computer ScienceTheory of Computing Systems

The results imply undecidability of a number of decision problems of unary conjunctive grammars, as well as non-existence of a recursive function bounding the growth rate of the generated languages.

Underlying Principles and Recurring Ideas of Formal Grammars

- Computer ScienceLATA
- 2018

The paper investigates some of the fundamental ideas of the context-free grammar theory, as they are applied to several extensions and subclasses of context- Free Grammar, including multi-component grammars, tree-adjoining grammARS, conjunctivegrammars and Boolean Grammars.

Linear Conjunctive Grammars and One-turn Synchronized Alternating Pushdown Automata

- Computer ScienceInt. J. Found. Comput. Sci.
- 2009

A subfamily of synchronized alternating pushdown automata is introduced, one-turn synchronized alternating Pushdown Automata, which accept the same class of languages as those generated by linear conjunctive grammars, thus strengthening the claim of synchronised alternating push down automata as a natural counterpart of conj unctive Grammars.

On Computational Universality in Language Equations

It is shown that resolved systems with two variables and two equations are as expressive as more complicated systems, while one-variable equations are “almost” as expressive.

Conjunctive Grammars, Cellular Automata and Logic

- Computer ScienceAUTOMATA
- 2021

This work expresses the rules of a conjunctive grammar in two Horn logics, which exactly characterize the complexity classes RealTime1CA and RealTime2OCA, which are both real-time one-dimensional one-way cellular automata.

It is proved that conjunctive grammars can still be parsed in cubic time and that the notion of the derivation tree is retained, which gives reasonable hope for their practical applicability.

Every system of this kind of language equations that are resolved with respect to variables and contain the operations of concatenation, union and intersection is proved to have a least fixed point, and the equivalence of these systems to conjunctive grammars is established.

This chapter is devoted to context-free languages, which were designed initially to formalize grammatical properties of natural languages and grammars and appeared to be well adapted to the formal description of the syntax of programming languages.
