Semi-chiral operators in 4d N $$ \mathcal{N} $$ = 1 gauge theories

Journal of High Energy Physics
We discuss the properties of quarter-BPS local operators in four-dimensional N $$ \mathcal{N} $$ = 1 supersymmetric Yang-Mills theory using the formalism of holomorphic twists.

On the approximation to algebraic numbers by algebraic numbers

Glasnik Matematicki, 2009
Let n be a positive integer. Let ξ be an algebraic real number of degree greater than n. It follows from a deep result of W. M. Schmidt that, for every positive real number e, there are infinitely many algebraic numbers α of degree at most n such that |ξ−α| < H(α)−n−1+e, where H(α) denotes the naive height of α. We sharpen this result by replacing e by

Individual differences in algebraic cognition: Relation to the approximate number and semantic memory systems [PDF]

Journal of Experimental Child Psychology, 2015
The relation between performance on measures of algebraic cognition and acuity of the approximate number system (ANS) and memory for addition facts was assessed for 171 ninth graders (92 girls) while controlling for parental education, sex, reading achievement, speed of numeral processing, fluency of symbolic number processing, intelligence, and the ...

AN EVOLUTIONARY ALGORITHM DETERMINING A DEFUZZYFICATION FUNCTIONAL

TASK Quarterly, 2007
Order fuzzy numbers are defined that make it possible to deal with fuzzy inputs quantitatively, exactly in the same way as with real numbers, together with four algebraic operations.

Two estimates concerning classical Diophantine approximation constants [PDF]

, 2013
In this paper we aim to prove two inequalities involving the classical approximation constants $w_{n}^{\prime}(\zeta),\hat{w}_{n}^{\prime}(\zeta)$ that stem from the simultaneous approximation problem $|\zeta^{j}x-y_{j}|$, $1\leq j\leq n$, on the one ...

Badly approximable numbers over imaginary quadratic fields

, 2018
We recall the notion of nearest integer continued fractions over the Euclidean imaginary quadratic fields $K$ and characterize the "badly approximable" numbers, ($z$ such that there is a $C(z)>0$ with $|z-p/q|\geq C/|q|^2$ for all $p/q\in K$), by ...

Diagonal quartic surfaces and transcendental elements of the Brauer group [PDF]

, 2017
We exhibit central simple algebras over the function field of a diagonal quartic surface over the complex numbers that represent the 2-torsion part of its Brauer group.

Diophantine approximation by conjugate algebraic integers

, 2003
Building on work of Davenport and Schmidt, we mainly prove two results. The first one is a version of Gel'fond's transcendence criterion which provides a sufficient condition for a complex or $p$-adic number $\xi$ to be algebraic in terms of the ...

An algebraic method to calculate parameter regions for constrained steady-state distribution in stochastic reaction networks

, 2018
Steady state is an essential concept in reaction networks. Its stability reflects fundamental characteristics of several biological phenomena such as cellular signal transduction and gene expression.
