Ricci-flat and Einstein pseudoriemannian nilmanifolds

open access: yesComplex Manifolds, 2019
This is partly an expository paper, where the authors’ work on pseudoriemannian Einstein metrics on nilpotent Lie groups is reviewed. A new criterion is given for the existence of a diagonal Einstein metric on a nice nilpotent Lie group.

Nilpotent Fuzzy Subgroups

open access: yesMathematics, 2018
In this paper, we introduce a new definition for nilpotent fuzzy subgroups, which is called the good nilpotent fuzzy subgroup or briefly g-nilpotent fuzzy subgroup.

Some results on schur multiplier of pairs of groups [PDF]

open access: yesMathematics and Computational Sciences, 2021
In this paper , we study the concept of the c-nilpotent multiplier of a pair of groups and prove that the c-nilpotent multipliers of perfect pairs of groups are isomorphic .Also, we prove an inequality for the order of the Schur multiplier of a pair of ...

Hilbert's theorem 90 for finite nilpotent groups [PDF]

open access: yesInternational Journal of Group Theory, 2021
‎In this note we prove an analog of Hilbert's theorem 90 for finite nilpotent groups‎. ‎Our version of Hilbert's theorem 90 was inspired by the Boston--Bush--Hajir (BBH) heuristics in number theory and will be useful in extending the BBH heuristics ...

Equations in virtually class 2 nilpotent groups [PDF]

open access: yesGroups, Complexity, Cryptology, 2022
We give an algorithm that decides whether a single equation in a group that is virtually a class $2$ nilpotent group with a virtually cyclic commutator subgroup, such as the Heisenberg group, admits a solution.

Nilpotent groups are round [PDF]

open access: yesIsrael Journal of Mathematics, 2008
We define a notion of roundness for finite groups. Roughly speaking, a group is round if one can order its elements in a cycle in such a way that some natural summation operators map this cycle into new cycles containing all the elements of the group. Our main result is that this combinatorial property is equivalent to nilpotence.

Towards semi-classical analysis for sub-elliptic operators

open access: yesBruno Pini Mathematical Analysis Seminar, 2022
We discuss the recent developments of semi-classical and micro-local analysis in the context of nilpotent Lie groups and for sub-elliptic operators.

On finite-by-nilpotent profinite groups [PDF]

open access: yesInternational Journal of Group Theory, 2020
Let $\gamma_n=[x_1,\ldots,x_n]$ be the $n$th lower central word‎. ‎Suppose that $G$ is a profinite group‎ ‎where the conjugacy classes $x^{\gamma_n(G)}$ contains less than $2^{\aleph_0}$‎ ‎elements‎ ‎for any $x \in G$‎.
