Singular dimensions of the N=2 superconformal algebras. I [PDF]

open access: yes, 1998
Verma modules of superconfomal algebras can have singular vector spaces with dimensions greater than 1. Following a method developed for the Virasoro algebra by Kent, we introduce the concept of adapted orderings on superconformal algebras.

Role of Shift Vector in High-Harmonic Generation from Noncentrosymmetric Topological Insulators under Strong Laser Fields

open access: yesPhysical Review X, 2022
As a promising avenue to obtain a new extreme ultraviolet light source and detect electronic properties, high-harmonic generation (HHG) has been actively developed in both theory and experiment.

*—Inductive limits and partition of unity

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1989
In this note we define and discuss some properties of partition of unity on *-inductive limits of topological vector spaces. We prove that if a partition of unity exists on a *-inductive limit space of a collection of topological vector spaces, then it ...

Topological Analysis on the Belief Rule Base Space

open access: yesIEEE Access, 2019
The belief rule base (BRB) uses the “IF-THEN” rule to handle different types of information under uncertainty, and then transforms them into a unified result in the same belief structure as the input.

Unlinking and unknottedness of monotone Lagrangian submanifolds [PDF]

open access: yes, 2012
Under certain topological assumptions, we show that two monotone Lagrangian submanifolds embedded in the standard symplectic vector space with the same monotonicity constant cannot link one another and that, individually, their smooth knot type is ...

Free Subspaces of Free Locally Convex Spaces

open access: yesJournal of Function Spaces, 2018
If X and Y are Tychonoff spaces, let L(X) and L(Y) be the free locally convex space over X and Y, respectively. For general X and Y, the question of whether L(X) can be embedded as a topological vector subspace of L(Y) is difficult.

Quantifying some distance topological properties of the non-zero component graph

open access: yesAIMS Mathematics, 2021
Several bioactivities of chemical compounds in a molecular graph can be expected by using many topological descriptors. A topological descriptor is a numeric quantity which quantify the topology of a graph.

Peano curves on topological vector spaces [PDF]

open access: yesLinear Algebra and its Applications, 2014
The starting point of this paper is the existence of Peano curves, that is, continuous surjections mapping the unit interval onto the unit square. From this fact one can easily construct of a continuous surjection from the real line $\mathbb{R}$ to any Euclidean space $\mathbb{R}^n$.

Crystalline gauge fields and quantized discrete geometric response for Abelian topological phases with lattice symmetry

open access: yesPhysical Review Research, 2021
Clean isotropic quantum Hall fluids in the continuum possess a host of symmetry-protected quantized invariants, such as the Hall conductivity, shift, and Hall viscosity.

The partition bundle of type A_{N-1} (2, 0) theory [PDF]

open access: yes, 2006
Six-dimensional (2, 0) theory can be defined on a large class of six-manifolds endowed with some additional topological and geometric data (i.e. an orientation, a spin structure, a conformal structure, and an R-symmetry bundle with connection).
