Partition functions, which enumerate the distinct ways a positive integer may be expressed as a sum of positive integers, have long captivated mathematicians due to their deep connections with number ...

NIST has released a five-chapter preview of the much-anticipated online Digital Library of Mathematical Functions. In development for over a decade, the DLMF is designed to be a modern successor to a ...

For novices, functions are one of the most intimidating features of OpenOffice.org's Calc. Newcomers quickly learn that functions are a main feature of spreadsheets, but there are almost four hundred, ...

Mathematical methods and special functions have long served as the backbone of modern theoretical physics and applied mathematics. These tools enable researchers to solve complex differential ...

Presburger arithmetic is the first-order theory of the natural numbers with addition (but no multiplication). We characterize sets that can be defined by a Presburger formula as exactly the sets whose ...

The Handbook of Mathematical Functions by Milton Abramovich and Irene Stegun is the one book I would wish to have on a desert island. Unlike a novel, it withstands infinities of rereadings. Its ...

A rule for creating a "y" output from an "x" input. For example, the y value of the function f(x) = 15x is 30 if x is 2. THIS DEFINITION IS FOR PERSONAL USE ONLY. All other reproduction requires ...

A Norwegian study shows that two-year-olds with poor motor function also exhibit poor mathematical skills. This knowledge will make it easier for teachers to identify children who may need extra help.
