Abstract
Recently the third named author defined a 2-parametric family of groups \(G_{n}^{k}\) [12]. Those groups may be regarded as a certain generalisation of braid groups. Study of the connection between the groups \(G_{n}^{k}\) and dynamical systems led to the discovery of the following fundamental principle: ‘‘If dynamical systems describing the motion of \(n\) particles possess a nice codimension one property governed by exactly \(k\) particles, then these dynamical systems admit a topological invariant valued in \(G_{n}^{k}\)’’.The \(G_{n}^{k}\) groups have connections to different algebraic structures, Coxeter groups and Kirillov–Fomin algebras, to name just a few. Study of the \(G_{n}^{k}\) groups led to, in particular, the construction of invariants, valued in free products of cyclic groups.In the present paper we prove that word and conjugacy problems for certain \(G_{k+1}^{k}\) groups are algorithmically solvable.中文翻译:
