A Group with Deep Pockets for All Finite Generating Sets
نویسندگان
چکیده
We show that the discrete Heisenberg group has unbounded deadend depth with respect to every finite generating set. We also show that, in contrast, it has bounded retreat depth.

متن کاملIrredundant Generating Sets of Finite Nilpotent Groups
It is a standard fact of linear algebra that all bases of a vector space have the same cardinality, namely the dimension of the vector space over its base field. If we treat a vector space as an additive abelian group, then this is equivalent to saying that an irredundant generating set for a vector space must have cardinality equal to the dimension of the vector space. The same is not true for...
متن کاملOn Groups whose Geodesic Growth is Polynomial
This note records some observations concerning geodesic growth functions. If a nilpotent group is not virtually cyclic then it has exponential geodesic growth with respect to all finite generating sets. On the other hand, if a finitely generated group G has an element whose normal closure is abelian and of finite index, then G has a finite generating set with respect to which the geodesic growt...
متن کاملEffect of Antimicrobial Photodynamic Therapy as an Adjunct to Nonsurgical Treatment of Deep Periodontal Pockets: A Clinical Study.
Introduction: Deep periodontal pockets pose a great challenge for nonsurgical periodontal treatment. Scaling and root planing (SRP) alone may not suffice in cases where surgical therapy cannot be undertaken. Various recent studies have suggested the use of antimicrobial Photodynamic Therapy (aPDT) for the management of periodontal infections. The aim of this study was to evaluate the effects of...
