On Finite Interpolation Property of Inner Automorphism Nearrings

, 2015
[[abstract]]In this note, the nite interpolation property of inner automorphism nearrings on groups is studied. We generalize Meldrum's result and show that the ideal I(G;H) of the nearring I(G) has nite interpolation property on H when H is a nonabelian

Deficiency One Parallelisms of PG(5, 2)

Mathematics
A spread in PG(n, q) is a set of lines such that each point is in exactly one line. A parallelism is a partition of the set of lines of PG(n, q) to spreads. A deficiency one parallelism is a parallelism with exactly one missing spread.

On Automorphisms of Line-graphs

European Journal of Combinatorics, 1980
This paper generalizes some results on hypergraph reconstruction due to \textit{C. Berge} [C. R. Acad. Sci., Paris, Ser. A 274, 1783-1786 (1972; Zbl 0236.05129)] and \textit{J.C.Fournier} [Proc. 1rst Working Sem. Hypergraphs, Columbus 1972, Lecture Notes Math. 411, 95-98 (1974; Zbl 0302.05113)].

Large automorphism groups of bordered tori

We study large groups of automorphisms of compact orientable bordered Klein surfaces of topological genus one. Here, large means that the order of the group is greater than or equal to 4(g−1), where g ≥ 2 is the algebraic genus of the surface.

Endomorphism near-rings of 𝑝-groups generated by the automorphism and inner automorphism groups

, 1993
The purpose of this paper is to investigate the equality of the endomorphism near-rings generated by the automorphism group and inner automorphism group of a nonabelian p p -group G G . If the automorphism group of

Weak limits of powers of Chacon's automorphism

, 2015
International audienceWe completely describe the weak closure of the powers of the Koopman operator associated to Chacon's classical automorphism. We show that weak limits of these powers are the ortho-projector to constants and an explicit family of ...

Permutation matrices and matrix equivalence over a finite field

International Journal of Mathematics and Mathematical Sciences, 1981
Let F=GF(q) denote the finite field of order q and Fm×n the ring of m×n matrices over F. Let 𝒫n be the set of all permutation matrices of order n over F so that 𝒫n is ismorphic to Sn.

Centralizers of automorphisms permuting free generators

Open Mathematics, 2019
By σ ∈ Skm we denote a permutation of the cycle-type km and also the induced automorphism permuting subscripts of free generators in the free group Fkm.

Involutions of the Moduli Space of Principal E₆-Bundles over a Compact Riemann Surface

Axioms
In this paper, the fixed points of involutions on the moduli space of principal E6-bundles over a compact Riemann surface X are investigated. In particular, it is proved that the combined action of a representative σ of the outer involution of E6 with ...
