Class-preserving Coleman automorphisms of some classes of finite groups
The normalizer problem of integral group rings has been studied extensively in recent years due to its connection with the longstanding isomorphism problem of integral group rings.

Classification of Lie Subalgebras up to an Inner Automorphism [PDF]
In this paper, a useful classification of all Lie subalgebras of a given Lie algebraup to an inner automorphism is presented. This method can be regarded as animportant connection between differential geometry and algebra and has many applications in ...

Orthogonal Inner Product Graphs over Finite Fields of Odd Characteristic
Let Fq be a finite field of odd characteristic and 2ν+δ≥2 be an integer with δ=0,1, or 2. The orthogonal inner product graph Oi2ν+δ,q over Fq is defined, and a class of subgroup of the automorphism groups of Oi2ν+δ,q is determined.

Strongly Ad-Nilpotent Elements of the Lie Algebra of Upper Triangular Matrices
In this paper, the strongly ad-nilpotent elements of the Lie algebra tn,ℂ of upper triangular complex matrices are studied. We prove that all the nilpotent matrices in tn,ℂ are strongly ad-nilpotent if and only if n≤6. Additionally, we prove that all the

On the Inner Automorphisms of a Compact Group [PDF]
In this note, we give a characterization of inner automorphisms in the set of automorphisms of a compact connected group, and then apply it to give a proof of a theorem due to K. Iwasawa on the group of automorphisms of a compact group.

On inner automorphisms and certain central automorphisms of groups [PDF]
Let G be a group, let M and N be two normal subgroups of G. We denote by AutNM (G), the set of all automorphisms of G which centralize G/M and N. In this paper we investigate the structure of a group G in which one of the Inn(G) = AutNM (G), AutNM(G) ≤ Inn(G) or Inn(G) ≤ AutNM(G) holds.

An application of Lie groupoids to a rigidity problem of 2-step nilmanifolds [PDF]
We study a problem of isometric compact 2-step nilmanifolds $M/\Gamma$ using some information on their geodesic flows, where $M$ is a simply connected 2-step nilpotent Lie group with a left invariant metric and $\Gamma$ is a cocompact discrete subgroup ...

$p$-Groups for which each outer $p$-automorphism centralizes only $p$ elements [PDF]
An automorphism of a group is called outer if it is not an inner automorphism. Let $G$ be a finite $p$-group. Then for every outer $p$-automorphism $\phi$ of $G$ the subgroup $C_G(\phi)=\{x\in G \;|\; x^\phi=x\}$ has order $p$ if and only if $G$ is of ...
