Number theory

open access: yesIEEE potentials, 1989
Number theory, an abstract branch of mathematics that deals with relationships between whole numbers, has provided highly useful answers to numerous real-world problems.

On the quadratic residues and their distribution properties

open access: yesOpen Mathematics, 2023
The main purpose of this article is to use elementary methods and properties of classical Gauss sums to determine identities for the number of residue systems of aa mod pp such that aa, a+a¯a+\bar{a}, and a−a¯a-\bar{a} are all quadratic residues ...

Supervised Machine Learning Classification for Short Straddles on the S&P500

open access: yesRisks, 2022
In this paper, we apply machine learning models to execute certain short-option strategies on the S&P500. In particular, we formulate and focus on a supervised classification task which decides if a plain short straddle on the S&P500 should be executed ...

On the number of decomposable trees [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2006
A tree is called $k$-decomposable if it has a spanning forest whose components are all of size $k$. Analogously, a tree is called $T$-decomposable for a fixed tree $T$ if it has a spanning forest whose components are all isomorphic to $T$. In this paper,

The Complexity of Number Theory

open access: yes, 2020
The Goldbach's conjecture has been described as the most difficult problem in the history of Mathematics. This conjecture states that every even integer greater than 2 can be written as the sum of two primes. This is known as the strong Goldbach's conjecture.

Crystal constructions in Number Theory

open access: yes, 2018
Weyl group multiple Dirichlet series and metaplectic Whittaker functions can be described in terms of crystal graphs. We present crystals as parameterized by Littelmann patterns and we give a survey of purely combinatorial constructions of prime power ...

Algorithms in Number Theory [PDF]

open access: yes, 1990
Publisher Summary This chapter discusses algorithms that solve two basic problems in computational number theory—factoring integers into prime factors and finding discrete logarithms. In the factoring problem, one is given an integer n 1 and is asked to find the decomposition of n into prime factors.

Perturbed Keplerian Hamiltonian Systems

open access: yesInternational Journal of Differential Equations, 2023
This paper deals with a class of perturbation planar Keplerian Hamiltonian systems, by exploiting the nondegeneracy properties of the circular solutions of the planar Keplerian Hamiltonian systems, and by applying the implicit function theorem, we show ...

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.
