Towards Formulation of a Complex Binary Number System

open access: yesSultan Qaboos University Journal for Science, 2002
For years complex numbers have been treated as distant relatives of real numbers despite their widespread applications in the fields of electrical and computer engineering.

The GL_2 main conjecture for elliptic curves without complex multiplication [PDF]

open access: yes, 2004
The main conjectures of Iwasawa theory provide the only general method known at present for studying the mysterious relationship between purely arithmetic problems and the special values of complex L-functions, typified by the conjecture of Birch and ...

Montgomery Reduction for Gaussian Integers

open access: yesCryptography, 2021
Modular arithmetic over integers is required for many cryptography systems. Montgomery reduction is an efficient algorithm for the modulo reduction after a multiplication. Typically, Montgomery reduction is used for rings of ordinary integers.

Eigenvalue Estimates of the ${\rm spin}^c$ Dirac Operator and Harmonic Forms on K\"ahler-Einstein Manifolds [PDF]

open access: yes, 2015
We establish a lower bound for the eigenvalues of the Dirac operator defined on a compact K\"ahler-Einstein manifold of positive scalar curvature and endowed with particular ${\rm spin}^c$ structures.

On-line algorithms for multiplication and division in real and complex numeration systems [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2019
A positional numeration system is given by a base and by a set of digits. The base is a real or complex number $\beta$ such that $|\beta|>1$, and the digit set $A$ is a finite set of digits including $0$. Thus a number can be seen as a finite or infinite

Musings on multiplication tables and associated mathematics and teaching practices

open access: yesPythagoras, 2009
This paper is based on my reflections on a deceptively simple tabular representation of a combined 12×12 multiplication table showing multiplier and multiplicand,starting at a time when I taught mathematics full time at a primary (elementary) school

Noise-enhanced computation in a model of a cortical column [PDF]

open access: yes, 2005
Varied sensory systems use noise in order to enhance detection of weak signals. It has been conjectured in the literature that this effect, known as stochastic resonance, may take place in central cognitive processes such as the memory retrieval of ...

Construction of dual-generalized complex Fibonacci and Lucas quaternions

open access: yesKarpatsʹkì Matematičnì Publìkacìï, 2022
The aim of this paper is to construct dual-generalized complex Fibonacci and Lucas quaternions. It examines the properties both as dual-generalized complex number and as quaternion. Additionally, general recurrence relations, Binet's formulas, Tagiuri's (

Migraine: Multiple Processes, Complex Pathophysiology [PDF]

open access: yesThe Journal of Neuroscience, 2015
Migraine is a common, multifactorial, disabling, recurrent, hereditary neurovascular headache disorder. It usually strikes sufferers a few times per year in childhood and then progresses to a few times per week in adulthood, particularly in females.

The merits and limitations of local impact ionization theory [PDF]

open access: yes, 2000
Multiplication measurements on GaAs p+-i-n+s with i-region thicknesses, w, between 1 μm and 0.025 μm and Monte Carlo (MC) calculations of the avalanche process are used to investigate the applicability of the local ionization theory.
