  2. Generalized Group Presentations and Formal Deformations of Cw Complexes

    A Peiffer-Whitehead word system W, or generalized group presentation, consists of generators for a free group and words of various orders n (GREATERTHEQ) 2 representing elements of the free group (n = 2), a free crossed module (n = 3) or a free module (n > 3). The P(,n)-equivalence relation on word …

  3. The Dehn function, word problem, and bounded word problem for finitely generated decidable group presentations

    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. For finitely generated decidable group presentations, this is not always the case. The main result of the present work is to …

  7. Restriction Semigroups: Structure, Varieties and Presentations

    Classes of (left) restriction semigroups arise from partial transformation monoids and form a wider class than inverse semigroups. Firstly, we produce a presentation of the Szendrei expansion of a monoid, which is a left restriction monoid, using a similar approach to Exel's presentation for the …
