Next year im gonna write a degree project/thesis in mathematics.
Do you have any suggestions or do you know a webpage with
lists of possible degree projects. Preferably Mathematical Physics.

That's a rather broad request. What are your interests? What issues in Math and Physics excite you?

I am pretty sure mathematics (or just algebra) is based on the assumption that -1*1=-1. Otherwise, we can't prove -1*(-1)=1.

Look into how mathematics might, if it does, change if we change it to -1*1=1. Therefore, 1*1=-1. Which means, sqrt(-1) is defined.

Probably easy to solve, but I'm curious to know what happens at the higher levels of mathematics.

Start reading books/papers on the areas that you're interested in. Soon you'll find a place where you can contribute. )

best of luck!

what's the square root of one in your system? And anyway, I thought 1 was defined as the multiplicative identity. I don't see how this system could be meaningful, or even consistent.

Square root of one doesn't "exist".

You can check that using the fundamental laws of algebra.

All you're doing is interchanging the representations of the additive identity and its additive inverse.

In any case, the square root of -1 is defined.
