Discrete Calculus: Applied Analysis on Graphs for Computational Science by Leo J. GradyEnglish | PDF,EPUB | 2010 | 371 Pages | ISBN : 1849962898 | 16.51 MB
The field of discrete calculus, also known as "discrete exterior calculus", focuses on finding a proper set of definitions and differential operators that make it possible to operate the machinery of multivariate calculus on a finite, discrete space. In contrast to traditional goals of finding an accurate discretization of conventional multivariate calculus, discrete calculus establishes a separate, equivalent calculus that operates purely in the discrete space without any reference to an underlying continuous process.
