Some Challenging Group Presentations
We study some challenging presentations which arise as groups of deeciency zero. In four cases we settle niteness: we show that two presentations are for nite groups while two are for innnite groups. Thus we answer three explicit questions in the literature and we provide the rst published deeciency zero presentation for a group with soluble length seven. The tools we use are coset enumeration ...
متن کاملComplete Positive Group Presentations
A combinatorial property of prositive group presentations, called completeness, is introduced, with an effective criterion for recognizing complete presentations, and an iterative method for completing an incomplete presentation. We show how to directly read several properties of the associated monoid and group from a complete presentation: cancellativity or existence of common multiples in the...
متن کاملEthnic self-awareness as a function of ethnic group status, group composition, and ethnic identity orientation.
This study found that ethnic self-awareness (i.e., the extent to which people are consciously aware of their ethnicity at any given moment) has different meanings for European Americans and Asian Americans and for Asian Americans with different ethnic identity orientations. The authors found main effects of ethnic group status and ethnic composition on ethnic self-awareness when comparing Asian...
متن کاملEthnic - Group Terms
Latin Americans and their descendants abroad have often thought about their identity as an ethnic group. In connection with this, a number of Latin American philosophers and social scientists working in the United States have independently questioned which term, if any, is adequate for reference (and self-reference) to that group. In their attempt to come up with correct answers, they have deve...
متن کاملPresentations of Generalisations of Thompson’s Group V
We consider generalisations of Thompson’s group V , denoted by Vr(Σ), which also include the groups of Higman, Stein and Brin. It was shown in [20] that under some mild conditions these groups and centralisers of their finite subgroups are of type F∞. Under more general conditions we show that the groups Vr(Σ) are finitely generated and, under the mild conditions mentioned above for which they ...
