Error estimates for the Gregory-Leibniz series and the alternating harmonic series using Dalzell integrals
Diego Rattaggi
The computation of Dalzell integrals gives new error estimates for the partial sums of the Gregory-Leibniz series $1 - \frac{1}{3} +…
On direct product subgroups of
Diego Rattaggi
Let be a subgroup of such that the two factors and are non-trivial groups. We show that if is not abelian,…
Counting -BM relations and classifying -BM groups
Diego Rattaggi
In the first part, we prove that the number of -BM relations is , which was conjectured by Kimberley. In the second part, we construct…
Abelianization conjectures for some arithmetic square complex groups
Diego Rattaggi
We extend a conjecture of Kimberley-Robertson on the abelianizations of certain square complex groups.
An incoherent simple group
Diego Rattaggi
We give an example of a finitely presented simple group containing a finitely generated subgroup which is not finitely presented.
Three amalgams with remarkable normal subgroup structures
Diego Rattaggi
We construct three groups , , , which can all be decomposed as amalgamated products and have very few normal subgroups of finite or infinit…
