In this technical paper, the authors develop precise results on the index of nilpotence of a derivation \(D\) of a semiprime ring \(R\) with characteristic, and also on a related index defined by the ideals of \(R\). Let \(R\) be a semiprime ring with characteristic zero or a prime, \(Q\) the symmetric Martindale quotient ring of \(R\), \(C\) the ...

On groups covered by locally nilpotent subgroups [PDF]
Let N be the class of pronilpotent groups, or the class of locally nilpotent profinite groups, or the class of strongly locally nilpotent profinite groups. It is proved that a profinite group G is finite-by-N if and only if G is covered by countably many

Let \(\pi\) be a set of primes, and let \(G\) be a finite \(\pi\)-separable group. Isaacs has defined a canonical basis \(I_\pi(G)\) for the vector space of class functions on the set of \(\pi\)-elements in \(G\). The author calls an element \(\varphi\in I_\pi(G)\) nilpotent if \(\varphi\) is induced from an element \(\delta\in I_\pi(K)\) where \(K ...

Strongly 2T - Clean Rings [PDF]
An element a in a ring R is referred to be strongly 2T-clean (2 – STC element for short), a = Ω-Λ+u, where Ω,Λ are idempotent elements and u is a unit elements of order three.

Towards semi-classical analysis for sub-elliptic operators
We discuss the recent developments of semi-classical and micro-local analysis in the context of nilpotent Lie groups and for sub-elliptic operators.

de Sitter Vacua with a Nilpotent Superfield [PDF]
We study the arguments given in [ ] which suggest that the uplifting procedure in the KKLT construction is not valid. First we show that the modification of the SUSY breaking sector of the nilpotent superfield, as proposed in [ ], is not consistent with ...

We investigate a few special decompositions in arbitrary rings and matrix rings over indecomposable rings into nilpotent and idempotent elements. Moreover, we also define and study the nilpotent sum trace number of nilpotent matrices over an arbitrary ...

Multipliers of nilpotent Lie superalgebras [PDF]
In this article, first we prove that all finite dimensional special Heisenberg Lie superalgebras with even center have dimension for some non-negative integers m, n and are isomorphic to H(m, n).

Approximate lattices and Meyer sets in nilpotent Lie groups [PDF]
We show that uniform approximate lattices in nilpotent Lie groups are subsets of model sets. This extends Y.Meyer's theorem about quasi-crystals in Euclidean spaces. We derive from this structure theorem a characterisation of connected, simply connected,
