Quarter-BPS states, multi-symmetric functions and set partitions

open access: yesJournal of High Energy Physics, 2021
We give a construction of general holomorphic quarter BPS operators in N $$ \mathcal{N} $$ = 4 SYM at weak coupling with U(N) gauge group at finite N. The construction employs the Möbius inversion formula for set partitions, applied to multi-symmetric ...

Endo-permutation modules as sources of simple modules. [PDF]

open access: yes, 2003
The source of a simple $kG$-module, for a finite $p$-solvable group $G$ and an algebraically closed field $k$ of prime characteristic $p$, is an endo-permutation module (see~\cite{Pu1} or~\cite{Th}). L.

Computing in permutation groups without memory [PDF]

open access: yes, 2013
Funding: UK Engineering and Physical Sciences Research Council (EP/K033956/1)Memoryless computation is a new technique to compute any function of a set of registers by updating one register at a time while using no memory.

Prime order derangements in primitive permutation groups [PDF]

open access: yes, 2011
Let G be a transitive permutation group on a finite set Ω of size at least 2. An element of G is a derangement if it has no fixed points on Ω. Let r be a prime divisor of |Ω|.

Minimal and random generation of permutation and matrix groups [PDF]

open access: yes, 2012
We prove explicit bounds on the numbers of elements needed to generate various types of finite permutation groups and finite completely reducible matrix groups, and present examples to show that they are sharp in all cases.

Topics in computational group theory : primitive permutation groups and matrix group normalisers [PDF]

open access: yes, 2012
Part I of this thesis presents methods for finding the primitive permutation groups of degree d, where 2500 ≤ d < 4096, using the O'Nan-Scott Theorem and Aschbacher's theorem. Tables of the groups G are given for each O'Nan-Scott class.

Automorphisms of Some Magmas of Order $k+k^2$

open access: yesИзвестия Иркутского государственного университета: Серия "Математика", 2018
This paper is devoted to the study of automorphisms of finite magmas and to the representation of the symmetric permutation group $ S_k $ and some of its subgroups by automorphism groups of finite magmas.

Most primitive groups are full automorphism groups of edge-transitive hypergraphs [PDF]

open access: yes, 2014
We prove that, for a primitive permutation group G acting on a set X of size n, other than the alternating group, the probability that Aut (X,YG) = G for a random subset Y of X, tends to 1 as n → ∞.

Totally -closed finite groups with trivial Fitting subgroup

open access: yesBulletin of Mathematical Sciences
A finite permutation group [Formula: see text] is called [Formula: see text]-closed if [Formula: see text] is the largest subgroup of [Formula: see text] which leaves invariant each of the [Formula: see text]-orbits for the induced action on [Formula ...
