The Obligatory Activation of Practiced Complex Multiplication Facts and What it Tells Us About Models of Arithmetic Processing

open access: yesJournal of Numerical Cognition, 2016
Three experiments were conducted in which adults practiced complex multiplication problems (e.g., 4 x 17). In Experiments 1 and 2, after practice participants completed a number-matching task in which two digits (cues) were followed by a single digit ...

Introductory remarks on complex multiplication

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1982
Complex multiplication in its simplest form is a geometric tiling property. In its advanced form it is a unifying motivation of classical mathematics from elliptic integrals to number theory; and it is still of active interest.

Faltings heights of abelian varieties with complex multiplication [PDF]

open access: yes, 2015
Let M be the Shimura variety associated with the group of spinor similitudes of a rational quadratic space over of signature (n,2). We prove a conjecture of Bruinier-Kudla-Yang, relating the arithmetic intersection multiplicities of special divisors and ...

A framework for deterministic primality proving using elliptic curves with complex multiplication [PDF]

open access: yesMathematics of Computation, 2014
We provide a framework for using elliptic curves with complex multiplication to determine the primality or compositeness of integers that lie in special sequences, in deterministic quasi-quadratic time.

Planning and Self-Control, but not Working Memory, Directly Predict Multiplication Performance in Adults

open access: yesJournal of Numerical Cognition, 2017
Empirical evidence suggests that working memory (WM) is closely related to arithmetic performance. WM, which is the ability to monitor and update recent information, underlies various cognitive processes and behaviors including planning, self-regulation,

The cyclotomic Iwasawa main conjecture for Hilbert cusp forms with complex multiplication [PDF]

open access: yes, 2015
We deduce the cyclotomic Iwasawa main conjecture for Hilbert modular cuspforms with complex multiplication from the multivariable main conjecture for CM number fields.

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.

Individual Differences in Math Ability Determine Neurocognitive Processing of Arithmetic Complexity: A Combined fNIRS-EEG Study

open access: yesFrontiers in Human Neuroscience, 2019
Some individuals experience more difficulties with math than others, in particular when arithmetic problems get more complex. Math ability, on one hand, and arithmetic complexity, on the other hand, seem to partly share neural underpinnings.
