Generalization of Nambu–Hamilton Equation and Extension of Nambu–Poisson Bracket to Superspace

Universe, 2018
We propose a generalization of the Nambu–Hamilton equation in superspace R 3 | 2 with three real and two Grassmann coordinates. We construct the even degree vector field in the superspace R 3 | 2 by means of the right-hand sides

Certain unitary representations of the infinite symmetric group, II [PDF]

Nagoya Mathematical Journal, 1987
The infinite symmetric group is the discrete group of all finite permutations of the set X of all natural numbers. Among discrete groups, it has distinctive features from the viewpoint of representation theory and harmonic analysis. First, it is one of the most typical ICC-groups as well as free groups and known to be a group of non-type I.

On the cardinality of infinite symmetric groups [PDF]

Involve, a Journal of Mathematics, 2015
A new proof is given that the symmetric group of any set [math] with three or more elements, finite or infinite, has cardinality strictly greater than that of [math] . Use of the axiom of choice is avoided throughout.

A product decomposition of infinite symmetric groups [PDF]

Proceedings of the American Mathematical Society, 2002
We prove that for any infinite κ \kappa , the full symmetric group Sym ⁡ ( κ ) \operatorname {Sym}(\kappa ) is the product of at most 14 14 abelian subgroups. This is a strengthening of a recent result of M. Abért.

Mobile impurity in a two-leg bosonic ladder

Physical Review Research
We study the dynamics of a mobile impurity in a two-leg bosonic ladder. The impurity moves both along and across the legs and interacts with a bath of interacting bosonic particles present in the ladder. We use both analytical (Tomonaga-Luttinger liquid)

On the distance eigenvalues of Cayley graphs

پژوهش‌های ریاضی, 2022
In this paper, graphs are undirected and loop-free and groups are finite. By Cn, Kn and Km,n we mean the cycle graph with n vertices, the complete graph with n vertices and the complete bipartite graph with parts size m and n, respectively.

Long-range interacting many-body systems in the irrep basis

Physical Review Research
Spin models featuring infinite-range, homogeneous all-to-all interactions can be efficiently described due to the existence of a symmetry-restricted Hilbert subspace and an underlying classical phase-space structure.

Crystal structures of four gold(I) complexes [AuL2]+[AuX2]− and a by-product (L·LH+)[AuBr2]− (L = substituted pyridine, X = Cl or Br)

Acta Crystallographica Section E: Crystallographic Communications
Bis(2-methylpyridine)gold(I) dibromidoaurate(I), [Au(C6H7N)2][AuBr2], (1), crystallizes in space group C2/c with Z = 4. Both gold atoms lie on twofold axes and are connected by an aurophilic contact.
