Hello, I'm intvl, PhD, and I currently live in Brazil. I'm interested in mathematics, music and Japanese/ otaku, and these should be my focuses on Wikipedia.

Mathematics Information

I am interested mostly in algebra and algebraic geometry. Number theory, topology, metamathematics and the philosophy of probability are other interests too.

Music Information

I know how to read sheet music and I know a little about jazz and western classical music. I can play a few instruments, but I'm not particularly good at any single one.

Otaku Culture Information

I consume some otaku media, including anime, manga, light novels and eroge. I consume them mostly in Japanese, so in terms of application to Wikipedia I can check the original texts.
