Identical Particles and Permutation Group [PDF]
Second quantization is revisited and creation and annihilation operators areshown to be related, on the same footing both to the algebra h(1), and to the superalgebra osp(1|2) that are shown to be both compatible with Bose and Fermi statistics. The two

Diese Arbeit versucht, die Theorie der Permutationsgruppen vom « kategoriellen » Standpunkt aus zu betrachten. Es werden in naheliegender Weise der Begriff der Permutationsstruktur und der Begriff des Homomorphismus einer Permutationsstruktur eingefuhrt (Abschnitt 1).

On the diameter of permutation groups [PDF]
The authors give an asymptotic universal upper bound for the diameter of all Cayley graphs of all permutation groups of degree \(n\), namely, they show that for any set of permutations \(S\) in \(S_ n\), every permutation in the subgroup generated by \(S\) can be expressed as a product of length at most \(\exp((n\cdot\ln n)^{1/2}(1+o(1)))\) of factors ...

Quasi-permutation Representations of Borel and Parabolic Subgroups of Steinberg's triality groups [PDF]
If G is a finite linear group of degree n, that is, a finite group of automor-phisms of an n-dimensional complex vector space, or equivalently, a finite group of non-singular matrices of order n with complex coefficients, we shall say that G is a quasi ...

Series with Commuting Terms in Topologized Semigroups
We show that the following general version of the Riemann–Dirichlet theorem is true: if every rearrangement of a series with pairwise commuting terms in a Hausdorff topologized semigroup converges, then its sum range is a singleton.

Generation modulo the action of a permutation group [PDF]
Originally motivated by algebraic invariant theory, we present an algorithm to enumerate integer vectors modulo the action of a permutation group. This problem generalizes the generation of unlabeled graph up to an isomorphism.

Permutation polynomials and group permutation polynomials [PDF]
Permutation polynomials of the form xτf (x3) over a finite field give rise to group permutation polynomials. We give a group theoretic criterion and some other criteria in terms of symmetric functions and power functions.

Non-Nudgable Subgroups of Permutations [PDF]
Motivated by a problem from behavioral economics, we study subgroups of permutation groups that have a certain strong symmetry. Given a fixed permutation, consider the set of all permutations with disjoint inversion sets. The group is called non-nudgable,
