# Advent of Mathematical Symbols

Here, you find my short advent calender about mathematical symbols. Each video introduces a symbol that one uses in mathematics. You can also download the pdf versions of the videos here.

### Introduction

The first video is about the Kronecker Delta:

### Let’s get started

Let’s continue with the related Levi-Civita Symbol.

The next symbol is called Nabla.

And now the Factorial:

The Gamma Function is a generalisation of the last video:

For the Composition we use a special symbol:

The capital sigma we use to denote the Sum Symbol:

And the capital Pi is used for the Product Symbol:

Do you know the symbol for the Restriction of a function?

Some matrices you see in physics a lot: Pauli matrices.

Naturally a fundamental notation: Set Brackets.

The Big O notation is used in a lot of formulas.

Next, we look a the Binomial Coefficient

The Modulo notation is important when you work with numbers.

The next video is about the Beta Function.

Also a fundamental notation is given by the Map arrows.

For some formulas the Little o notation is helpful.

Next, let’s discuss the Outer product.

Are you interested in Euler’s Phi Function

The Laplace Operator a very important object in differential equations.

Next symbol ist about the Convolution

Do you know the Heaviside Function

Let us talk about Quaternions.

And finally the last video in this series is about Infinity.
