# “Real” Analysis Is a Degenerate Case of Discrete Analysis

@inproceedings{Zeilberger2004RealAI, title={“Real” Analysis Is a Degenerate Case of Discrete Analysis}, author={Doron Zeilberger}, year={2004} }

There are many ways to divide mathematics into two-culture dichotomies. An important one is the Discrete vs. the Continuous. Until almost the end of the 20th century, the continuous culture was dominant, as can be witnessed by notation. An important family of Banach spaces of continuous functions is denoted by L , with a Capital L, while their discrete analogs are denoted by the lowercase counterpart l. A function of a continuous variable is denoted by f(x), where the continuous output, f , is…

The results show that there do not exist arbitrarily accurate computer arithmetics for the reals that are associative rings and it is proved that a locally compact field cannot be approximated arbitrarily closely by finite rings.

Why I hate the Continuous and Love the Discrete I have always loved the discrete and hated the continuous. Perhaps it was the trauma of having to go through the usual curriculum of “rigorous” ,…

### Mathematical Rigor in Applied Mathematics Based on the Nonstandard Analysis

- MathematicsCommunications in Computer and Information Science
- 2021

A new axiomatic of set theory is introduced that includes vague definitions and concepts at the same level of rigor as in modern classical mathematics, which allows to consider some non-rigorous arguments of applied mathematics as rigorous ones and, thus, to be sure that they are consistent.

This article aims at bringing some light to the practical interest for the reliability engineer in using two discrete models among the most popular: the Inverse Polya distribution (IPD), based on a Polya urn scheme, and the so-called Weibull-1 (W1) model.
