INFINITE SYMMETRIC GROUPS [PDF]
Ars Comb., 2012 In this work, infinite similarities of permutation groups are investigated by means of new methods. For this purpose, we handle distinct groups on the set of natural numbers and we give the separation of the subgroups of them.

Maximal subsemigroups of infinite symmetric groups [PDF]
Bulletin of the Australian Mathematical SocietyIn 1994, Brazil, Covington, Penttila, Praeger and Woods provided a new family of maximal subgroups of the symmetric group G(X) defined on an infinite set X.

Symmetric quotients of knot groups and a filtration of the Gordian graph [PDF]
, 2020 We define a metric filtration of the Gordian graph by an infinite family of 1-dense subgraphs. The nth subgraph of this family is generated by all knots whose fundamental groups surject to a symmetric group with parameter at least n, where all meridians ...

The invariants of the third symmetric power representation of SL_2(F_p) [PDF]
, 2010 For a prime p>3, we compute a finite generating set for the SL_2(F_p)-invariants of the third symmetric power representation. The proof relies on the construction of an infinite SAGBI basis and uses the Hilbert series calculation of Hughes and ...

On Central Gap Numbers of Symmetric Groups
, 2008 g(G) denotes the central gap number of a group G. We show that for n ≥ 8, g(Sn) ≥ n and g(An) ≥ n-2. We give exact values of g(Sn) and g(An) for small n's. In particular, g(S9) = 9 and g(A9) = 7.

Cores of hyperbolic 3-manifolds and limits of Kleinian groups II [PDF]
, 1999 Troels Jørgensen conjectured that the algebraic and geometric limits of an algebraically convergent sequence of isomorphic Kleinian groups agree if there are no new parabolics in the algebraic limit.

Boundary maps and maximal representations on infinite dimensional Hermitian symmetric spaces [PDF]
, 2021 We define a Toledo number for actions of surface groups and complex hyperbolic lattices on infinite dimensional Hermitian symmetric spaces, which allows us to define maximal representations.

Finite and infinite element method applied to water wave diffraction problems [PDF]
, 1999 In this work, three types of infinite elements are developed to solve the problem of linear water wave diffraction by objects in a 2D unbounded domain. The infinite elements, which model the far field wave potential stretching to infinity, are coupled to

Topological groups and infinite graphs
, 1991 We show how results concerning infinite, locally finite, vertex-symmetric graphs can be related with the structure theory of topological groups, when the latter is applied to automorphism groups of the graphs. In particular, we discuss polynomial growth,
