## Discontinuous Analysis

## Calculus discontinuity fixed! Analysis of discontinuous functions.

## No limit of an arbitrary function? No root of -1? There is indeed a root of -1 and likewise there is a (generalized) limit of every function at every point, for all types of discontinuity in calculus. Learn to use it in practice for limits, sums, derivatives, integrals of arbitrary functions.

## For whom is discontinuous analysis?

Welcome to this thingy of non-continuous analysis: itās a calculus for mathematicians and advanced math for engineersĀ course. ThisĀ advanced calculusĀ is just a must for a physicist.Ā If you want to doĀ calculus self-study, this course in functional analysis and its applications to differential equations is for you, tooĀ (this course is not in university programs).Ā BecauseĀ discrete calculusĀ is of interest for software developers, I welcome programmers, too,Ā to learn a sound foundation ofĀ discrete analysis.

You will learn advancedĀ calculus tricksĀ allowing to formalizeĀ such things asĀ derivative of discontinuous function or sum of divergent series.Ā In general this course generalized any kind of calculus limitĀ from convergentĀ onlyĀ toĀ anyĀ divergent case.

Discontinuous analysisĀ allows to uniteĀ discrete calculusĀ (discrete derivative,Ā discrete integral) and the usual calculus into one powerful theoryĀ usingĀ general topology.Ā MyĀ generalized derivativeĀ (not the same asĀ generalized derivativeĀ inĀ distributionsĀ theory)Ā applies toĀ *any*Ā function whatsoever. The same applies to my generalized integral and generalized limit in general, as well as to divergent series math.

Derivative ofĀ non-continuous functionĀ is often not a number but an infinite dimensional vector.Ā Nevertheless, because it is a vector in a linear space, formulas like f'(x) ā f'(x) = 0 still apply,Ā what simplifies your calculations.Ā You can for example add, substrate, etc. infinite series without worrying whether they are convergent.Ā You can check convergence at the end of calculations.

I told that this is a must for physicist. Probably we will discover using this theory something new about black holes connecting general relativity and quantum mechanics into a new kind of quantum gravity theory ā share a Nobel Prize with me then. Anyway various topics about non-continuous analysis are perfect PhD research topics.

### Access Anytime Anywhere

You can learn while you are for example at home or in a train.

### Self Pace

There are no whatsoever restrictions of how fast or slow you learn. You are not required for example finish learning a chapter of a textbook during a week.

### Get Certified

You receive certificates your learning is worth.

## Video Introduction

## Available in the course:

### We start with a graphical explanation and then go into mathematical details.

### There are two definitions of generalized limit: an axiomatic one and a concrete one. In usual cases they are equivalent. Choose any of the two. You don't need to remember all the definitions when you just calculate, just follow simple rules.

### We take limits on "filters". That's a way to describe limits, upper limits, lower limits, ..., gradients, etc. with the same simple formulas, rather than repeating similar definitions over and over as you see in calculus books. It's not hard to understand.

### You learn some of general topology just by the way, without being taught it in a usual boring non-understandable way. You learn newest discoveries in general topology and it's easy.

### Support from Newton, err... the author.

### It uses the theory of "funcoids", a highly abstract thing from general topology. This course doesn't include detailed information on funcoids (just their definitions - several equivalent ones), so some proofs may be not understood by you (just believe me), but you can read about funcoids in freely available sources, if you want to check proofs.

### Course certification with simple exam questions will be added. Everybody who will pass receives "Master of discontinuous analysis" certificate!

### Apply it not only to continuous functions but also to discrete analysis (read: graph theory). Yes, you can apply analysis to graphs. Software developers!

### Victor Porton

Your instructor is Victor Porton, the person who discovered *ordered
semigroup actions* (and wrote 500 pages about them), a theory as
general as group theory but unknown before. Victor Porton is a
programming languages polyglot, author of multitudinous softwares
and programming libraries, blockchain expert and winner of
multitudinous blockchain hackathons, author of several books,
a philosopher.

Of course, there is no such thing. But there is a generalized definition of limit that does exist for every function at every point. That’s similar to root of -1: it does not exist in real numbers but exists for a wider set, complex numbers.

In discontinuous analysis all series, derivatives, integrals, etc. exist. This allows for example to cancel f'(x) – f'(x) = 0 for every function without first checking that the derivative exists. That simplifies your work. There is a conjectured quantum gravity theory based on discontinuous analysis.

It is applicable to functions on real numbers, complex numbers, vectors, infinite dimensional vectors, etc. The exact conditions are specified in the lessons, but it is applicable to a VERY broad class of spaces.

Mathematics for PhDs. Mathematicians! Engineers. Physicists! (If you are a physicist, you have no right not to take this course.) Economists? I think, economists. And you can apply this to graphs instead of continuous functions – software developers!

Functions between compact spaces are not yet well-researched in discontinuous analysis.

I remind that the theory of generalized functions orĀ distributionsĀ also allows to study functions with discontinuities and infinite values.

But to have for instance product of two generalized functions in terms of distributions, you need to check complex pre-conditions. In my theory, every algebraic operation defined on numbers is also defined for generalized “quantities”. So, you can freely multiple any two functions (if there is a multiplication in your space).

## Some things not ready

## State

My theory of quantum gravity is not checked for existence and uniqueness of of solutions. Solve it and share a Nobel Prize with me?

Discontinuous analysis on compacts is not yet described.
