I am a high-school student with a strong (borderline obsessive) interest in mathematics of every kind.

My contributions will be sporadic and diverse, with little overall direction. There are still some specific theorems I would like to see on, and I will (probably) eventually add them.

I will often attempt to contribute to fields of which I am not very familiar, by extrapolating from existing pages on this website and checking out books from the Internet Archive to use as sources. If I make a mistake, please correct it; I can handle constructive criticism.

Computability theory
I have been working on building a more comprehensive theory of computation on. Equivalence from recursive relations to Turing machines is now complete. The next step is to prove what I will call Symbol Reduction of Turing Machine, and will roughly give as:
 * Let $T$ be a Turing machine with $n$ input symbols.
 * There exists an equivalent machine $T'$ with $n + 1$ tape symbols.

After that, I will use methods similar to Minsky to emulate a $2$-symbol machine with a URM, completing the equivalence.

I've also started working with provability, but I need to go back and change all of by Robinson Axioms-based theorems to use Minimal Arithmetic instead. I will also need to construct a recursive proof-finder. From there, Godel's First Incompleteness Theorem should be in reach.

As a long-term goal, I want to formally construct a "practical" programming language, to help with algorithm design. It should be usable for computational complexity, so this will need to happen after we define Random Access Machines (which are crucial for fine-grained complexity). The paper that defines RAMs uses a language they call "RAM-ALGOL," a subset of ALGOL that immediately translates into a RAM. We could also use LISP, as the original version has a simple structure and a lot of discussion about the implementation.
