Tree algebra of sofic tree languages [PDF]
We consider the languages of finite trees called tree-shift languages which are factorial extensible tree languages. These languages are sets of factors of sub-shifts of infinite trees. We give effective syntactic characterizations of two classes of regular tree-shift languages: the finite type tree languages and the tree languages which are almost of ...

Temporal Logic and Model Checking for Operator Precedence Languages [PDF]
In the last decades much research effort has been devoted to extending the success of model checking from the traditional field of finite state machines and various versions of temporal logics to suitable subclasses of context-free languages and ...

Unambiguous Tree Languages Are Topologically Harder Than Deterministic Ones [PDF]
The paper gives an example of a tree language G that is recognised by an unambiguous parity automaton and is analytic-complete as a set in Cantor space.

Regular Languages of Thin Trees [PDF]
For a fixed alphabet \(A\), a \textit{forest} is a ``mapping from its set of nodes \(\mathrm{dom}(t)\subset\omega^+\) into \(A\)''. It is additionally assumed that ``a forest is finitely branching: for every \(w\in\omega^\ast\) there are only finitely many nodes of the form \(wn\) for \(n\in {\mathbb N}\) in \(\mathrm{dom}(t)\)''; these nodes (of the ...

Finite Automata with Generalized Acceptance Criteria [PDF]
We examine the power of nondeterministic finite automata with acceptance of an input word defined by a leaf language, i.e., a condition on the sequence of leaves in the automaton's computation tree.

On the Accuracy of Language Trees
Historical linguistics aims at inferring the most likely language phylogenetic tree starting from information concerning the evolutionary relatedness of languages. The available information are typically lists of homologous (lexical, phonological, syntactic) features or characters for many different languages.

Analyzing Indo-European Language Similarities Using Document Vectors
The evaluation of similarities between natural languages often relies on prior knowledge of the languages being studied. We describe three methods for building phylogenetic trees and clustering languages without the use of language-specific information ...
