This column is a forum for discussion of mathematical communities throughout the world, and through all time. Our definition of “mathematical community” is the broadest. We include “schools” of mathematics, circles of correspondence, mathematical societies, student organizations, and informal communities of cardinality greater than one. What we say about the communities is just as unrestricted. We welcome contributions from mathematicians of all kinds and in all places, and also from scientists… 

A short tale of two cities: Otto schreier and the Hamburg— Vienna connection

Conceptions for relating the evolution of mathematical concepts to mathematics learning—epistemology, history, and semiotics interacting

There is an over-arching consensus that the use of the history of mathematics should decidedly improve the quality of mathematics teaching. Mathematicians and mathematics educators show here a rare

A historical reconstruction of the connections between the Viennese neopositivists and the American pragmatists: economic theory in the project for the International Encyclopaedia of Unified Science

Persuaded by the fact that the philosophical debate in Vienna during the 1930s deeply influenced the subsequent American developments of economic theory, my purpose is to reconstruct, from a

Mathematical economics in Vienna between the Wars

Wald was the first who solved the existence problem in economics. His paper should be regarded as a starting point of the axiomatization in economics. The movement toward an axiomatization in

TLDR
An enhanced halftoning algorithm for which the filter weights and the quantizer thresholds vary depending on input pixel value is presented, which gets the ideal bi-pattern with reasonable ordered statistic and Blue-Noise spectrum characteristic and the aesthetic feeling settle for.

A simple and efficient error-diffusion algorithm

TLDR
A new error-diffusion scheme that is faster than the universally used Floyd-Steinberg algorithm, while maintaining its original simplicity, and applicable in a wide range of computer graphics applications, where a color quantization algorithm with good visual properties is needed.

Error Diffusion Using Half Toning in Color Images

TLDR
The proposed error diffusion method is based on half toning method, which is known as Floyd and Steinberg’s filter, and is faster than the previous methods, while preserving simplicity.

A Half-toning Method based on Error Diffusion

TLDR
A new error diffusion approach is proposed that provides high quality ED results based on half toning method, known as Floyd and Steinberg's filter, which is faster than conventional methods.

An Textile Color Degradation Algorithm Based on Spatial Gray Domain

TLDR
The algorithm gets the ideal bi-pattern with reasonable ordered statistic and Blue-Noise spectrum characteristic, and the aesthetic feeling settle for people's vision is obtained.
