Winding Number in String Field Theory

open access: yes, 2011
Motivated by the similarity between cubic string field theory (CSFT) and the Chern-Simons theory in three dimensions, we study the possibility of interpreting N=(\pi^2/3)\int(U Q_B U^{-1})^3 as a kind of winding number in CSFT taking quantized values. In

Entanglement Distillation Protocols and Number Theory

open access: yes, 2005
We show that the analysis of entanglement distillation protocols for qudits of arbitrary dimension $D$ benefits from applying basic concepts from number theory, since the set $\zdn$ associated to Bell diagonal states is a module rather than a vector ...

Algorithms in algebraic number theory [PDF]

open access: yes, 1992
In this paper we discuss the basic problems of algorithmic algebraic number theory. The emphasis is on aspects that are of interest from a purely mathematical point of view, and practical issues are largely disregarded. We describe what has been done and,

Impulse Propagation in Compositions and Words

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2021
We consider compositions of n represented as bargraphs and subject these to repeated impulses which start from the left at the top level and destroy horizontally connected parts.

Modular Construction of Topological Interlocking Blocks—An Algebraic Approach for Resource-Efficient Carbon-Reinforced Concrete Structures

open access: yesBuildings, 2023
An algebraic approach to the design of resource-efficient carbon-reinforced concrete structures is presented. Interdisciplinary research in the fields of mathematics and algebra on the one hand and civil engineering and concrete structures on the other ...

On the distribution of primitive roots and Lehmer numbers

open access: yesElectronic Research Archive, 2023
In this paper, we study the number of the Lehmer primitive roots solutions of a multivariate linear equation and the number of $ 1\leq x\leq p-1 $ such that for $ f(x)\in {\mathbb{F}}_p[x] $, $ k $ polynomials $ f(x+c_1), f(x+c_2), \ldots, f(x+c_k) $ are

Position of the maximum in a sequence with geometric distribution [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2005
As a sequel to [arch04], the position of the maximum in a geometrically distributed sample is investigated. Samples of length n are considered, where the maximum is required to be in the first d positions.

Fermi-Dirac statistics and the number theory

open access: yes, 2005
We relate the Fermi-Dirac statistics of an ideal Fermi gas in a harmonic trap to partitions of given integers into distinct parts, studied in number theory.

The unpredictably eruptive dynamics of spruce budworm populations in eastern Canada

open access: yesPopulation Ecology, EarlyView.
We examine historical population data for spruce budworm from several locations through the period 1930–1997, and use density‐dependent recruitment curves to test whether the pattern of population growth over time is more consistent with Royama's (1984; Ecological Monographs 54:429–462) linear R(t) model of harmonic oscillation at Green River New ...

Distribution of values of Hardy sums over Chebyshev polynomials

open access: yesAIMS Mathematics
This paper mainly studied the distribution of values of Hardy sums involving Chebyshev polynomials. By using the method of analysis and the arithmetic properties of Hardy sums and Chebyshev polynomials of the first kind, we obtained a sharp asymptotic ...
