About

Hi, I'm nullspace. It's hard to talk about oneself, so bear with me. I am in my mid-twenties and I study mathematics. My dream is to become so good at it, that I can work on harder problems.

How do I make this site

I use the static site generator lume. It still is just HTML but I like to organize content into separate files.

What is a nullspace?

Let $\mathbb K$ be a field and $A\in\mathbb{K}^{m\times n}$ a matrix. The set $$\{x\in \mathbb K^m : Ax=0\}\subseteq \mathbb K^n$$ is called the nullspace of $A$. It can be computed with the Gaussian Algorithm.
