On weak commutativity between isomorphic groups,
Said N. Sidki, Noraí R. Rocco, Ricardo N. de Oliveira +1
The Weak Commutativity Group was defined by the first author in the early 1980's as where and are iso…
Twisted Bracelets for Sorting by Transpositions: the Transposition Diameter of
Luiz A. G. Silva, Luis A. B. Kowada, Noraí R. Rocco +1
Sorting By Transpositions (SBT) seeks the minimum number of transpositions required to sort a permutation on symbols into the identity . Let . A cyclic-target pai…
The Non-Abelian Tensor Square of Finite Metacyclic Groups
Juliana Silva Canella, Norai Romeu Rocco
In this paper, we investigate the group , an extension of the non-abelian tensor square by the direct product , in order to determine a presentation of $G \oti…
On some series of a group related to the non-abelian tensor square of groups
Raimundo Bastos, Ricardo de Oliveira, Carmine Monetta +1
Let be a group. We denote by a certain extension of the non-abelian tensor square by . In this paper we prove that the derived subgroup …
Some Structural and Closure Properties of an Extension of the -tensor Product of Groups,
Ivonildes R. M. Dias, Eunice C. P. Rodrigues, Noraí R. Rocco
In this work we study some structural properties of the group , a non-negative integer, which is an extension of the -tensor product , where a…
A new 1.375-approximation algorithm for Sorting By Transpositions
L. A. G. Silva, L. A. B. Kowada, N. R. Rocco +1
In genome rearrangements, the mutational event transposition swaps two adjacent blocks of genes in one chromosome. The Transposition Distance Problem (TDP) aims to find the minimum…
