An Application of Word Combinatorics to Decision Problems in Group Theory

, 2010
In this work we develop a graph theoretical test on graphs corresponding to subgroups of one-relator groups with small cancellation condition which, if successful, implies that the subgroup under consideration has solvable membership problem with a simple solution.

An Elementary Construction of Unsolvable Word Problems in Group Theory

, 1973
Publisher Summary This chapter presents an elementary construction of unsolvable word problems in group theory and introduces a new approach to constructing finitely presented groups with unsolvable word problems. The argument has a concrete motivation that makes it easy to follow. The chapter also discusses arrow notation and presents a proof of the

Theory of mind and emotion recognition skills in children with specific language impairment, autism spectrum disorder and typical development: group differences and connection to knowledge of grammatical morphology, word‐finding abilities and verbal working memory

International Journal of Language & Communication Disorders, 2014
AbstractBackgroundSocial perception skills, such as understanding the mind and emotions of others, affect children's communication abilities in real‐life situations. In addition to autism spectrum disorder (ASD), there is increasing knowledge that children with specific language impairment (SLI) also demonstrate difficulties in their social perception ...

Modifying Sievers: A Theory Of Word Groups In Old English Meter [PDF]

, 1996
The classic explanation of Old English meter, Eduard Sievers' Theory of Five Types, has a number of faults. Because it offers a pragmatic description of verse-patterns rather than a justification for them, it is less a theory than a taxonomy. There is inconsistency as to where metrical stress occurs, and the role of resolution. The updated version by A.

Certain Simple, Unsolvable Problems of Group Theory. I1)1)Unless otherwise indicated, the results and proofs of this and subsequent related papers are as given (in somewhat more detail) in Several simple unsolvable problems of group theory related to the word problem, a doctoral dissertation accepted by Princeton University in April, 1952. The proof of the unsolvability of the quasi-MAGNUS problem was presented to a meeting of The Association for Symbolic Logic, April 28, 1951. (Abstract, …
