Continued fractions related to a group of linear fractional transformations
Open Mathematics, 2023 There are strong relations between the theory of continued fractions and groups of linear fractional transformations. We consider the group G3,3{G}_{3,3} generated by the linear fractional transformations a=1−1∕za=1-1/z and b=z+2b=z+2.

Cogent Psychology, 2018 In students in grades 4 to 9 (22 males, 20 females), two reading disability groups—dyslexia (n = 20) or oral and written language learning disability (OWL LD) (n = 6)—were compared to each other and two kinds of control groups—typical readers (n = 6) or ...

The Dehn function, word problem, and bounded word problem for finitely generated decidable group presentations [PDF]
, 2012 For finite group presentations, the word problem is solvable if and only if the Dehn function is computable. Additionally, the bounded word problem is always solvable.

Вестник Самарского университета: История, педагогика, филологияThe article deals with the issue of describing the pausal form of a word in the Arabic literary language, which existed within the framework of traditional grammar with its unique terminological base until the middle of the last century, and after it was

Topological model of composite fermions in the cyclotron band generator picture: New insights
Results in Physics, 2018 A combinatorial group theory in the braid groups is correlated with the unusual “anyon” statistic of particles in 2D Hall system in the fractional quantum regime well.

Что такое вид русского глагола? (теоретические модели описания русского вида)
Revue des études slaves, 2020 The article contains an overview of significantly different theoretical models of the Russian verb aspect: the “traditional” classifying category model (Russian Grammar 1980); the earlier inflectional category model (Karcevski, Isačenko, Maslov); the ...

On real-time word problems [PDF]
, 2003 It is proved that the word problem of the direct product of two free groups of rank 2 can be recognised by a 2-tape real-time but not by a 1-tape real-time Turing machine.

Frontiers in EducationPurposeThis study aims to investigate the impact of the lexico-phonological diglossic distance of story reading (a scaffolded storybook intervention, informed by Vygotsky’s theory of scaffolding and fading) on Arabic-speaking preschool children’s ...

Fox derivatives: a unique connection between group presentations and the integral group ring [PDF]
Advances in Group Theory and Applications, 2018 We give a criterion to determine whether generators can be removed from a finite presentation via Tietze transformations. We prove that for a generator in a pre- sentation ⟨X|R⟩ to be removable, there must exist a word in the normal closure of relators ...

Solving the word problem in real time [PDF]
, 2001 The paper is devoted to the study of groups whose word problem can be solved by a Turing machine which operates in real time. A recent result of the first author for word hyperbolic groups is extended to prove that under certain conditions the ...
