Subgroups of small Index in infinite Symmetric Groups
Bulletin of the London Mathematical Society, 1986 Let \(\Omega\) be an infinite set having cardinality \(n:=| \Omega |\), and let \(S:=Sym(\Omega)\) be its symmetric group having then cardinality \(2^ n\). Moreover, let G be a subgroup of S and let \(S_{\{\Delta \}}\) or \(G_{\{\Delta \}}\) be the setwise stabilizer of \(\Delta\) in S or in G, respectively, for each subset \(\Delta\subseteq \Omega ...

The cofinality spectrum of the infinite symmetric group [PDF]
Journal of Symbolic Logic, 1997 AbstractLetSbe the group of all permutations of the set of natural numbers. The cofinality spectrumCF(S)ofSis the set of all regular cardinalsλsuch thatScan be expressed as the union of a chain ofλproper subgroups. This paper investigates which setsCof regular uncountable cardinals can be the cofinality spectrum ofS.

On the transverse Scalar Curvature of a Compact Sasaki Manifold
Complex Manifolds, 2014 We show that the standard picture regarding the notion of stability of constant scalar curvature metrics in Kähler geometry described by S.K. Donaldson [10, 11], which involves the geometry of infinitedimensional groups and spaces, can be applied to the ...

Tensor models, Kronecker coefficients and permutation centralizer algebras
Journal of High Energy Physics, 2017 We show that the counting of observables and correlators for a 3-index tensor model are organized by the structure of a family of permutation centralizer algebras.

MAXIMAL SUBSEMIGROUPS OF INFINITE SYMMETRIC GROUPS
Bulletin of the Australian Mathematical SocietyAbstractBrazilet al. [‘Maximal subgroups of infinite symmetric groups’,Proc. Lond. Math. Soc. (3)68(1) (1994), 77–111] provided a new family of maximal subgroups of the symmetric group$G(X)$defined on an infinite setX. It is easy to see that, in this case,$G(X)$contains subsemigroups that are not groups, but nothing is known about nongroup maximal ...

The Index Problem for Infinite Symmetric Groups [PDF]
Proceedings of the American Mathematical Society, 1964 Let M be an infinite set with cardinal X, S(X, Y) = o-: ois a permutation on M such that I spt oj I d has no subgroups of index less than or equal Z. In this paper, the following generalization of these results is proven.

Науковий вісник Ужгородського університету. Серія: Математика і інформатика, 2020 Matrix representations of finite semigroups over fields are studied not so well as for finite groups. Representations of finite groups over fields are studied sufficiently well; in particular, the criterions of representation type are fully defined for ...

SELBERG ZETA FUNCTIONS OF INFINITE SYMMETRIC GROUPS
Kyushu Journal of Mathematics, 2004 From the author's abstract: ``The main purpose of this paper is to seek a reasonable formulation of Selberg zeta-functions of infinite symmetric groups and calculate actual candidates of them. In order to achieve this, we introduce a (Selberg-type) zeta-function attached to a finite group action \(G\to X\).
