On zero-symmetric nearrings with identity whose additive groups are simple
summary:We investigate conditions on an infinite simple group in order to construct a zero-symmetric nearring with identity on it. Using the Higman-Neumann-Neumann extensions and Clay's characterization, we obtain zero-symmetric nearrings with identity ...

Parity features for classes of the infinite symmetric group
Journal of Combinatorial Theory, Series A, 1982 AbstractA conjugacy class in the infinite-symmetric group is said to have parity features if no finitary odd permutation is a product of two of its members. The conjugacy classes having parity features are determined. The role played by a property of this kind in determining products of conjugacy classes in any group in which every element is conjugate

The homomorphic images of infinite symmetric groups
Forum Mathematicum, 1993 Let \(\kappa\) be an infinite cardinal and \(S(\kappa)\) the infinite symmetric group of all permutations of a set of cardinality \(\kappa\). If \(\omega \leq \lambda \leq \kappa\), let \(S_ \lambda(\kappa)\) be the normal subgroup of \(S(\kappa)\) comprising all permutations which move fewer then \(\lambda\) symbols.

Infinite dimensional symmetric spaces [PDF]
, 2005 In this work we study two different (but related) classes of infinite dimensional symmetric spaces. Starting with compact Lie groups and involutions of them we construct in the first chapter Hilbert manifolds endowed with weak Riemannian metrics.

Hydrogen‐Bond–Driven Ion Retention in Electrolyte‐Gated Synaptic Transistors
Advanced Functional Materials, EarlyView.Anion molecular design governs ion–polymer interactions in electrolyte‐gated synaptic transistors. Asymmetric anions induce hydrogen‐bond interactions that suppress ion back‐diffusion and stabilize doping, enabling enhanced nonvolatile synaptic properties.
