If someone is willing to briefly explain what these three branches of mathematics are about, I'd appreciate it. I don't even understand if they are three completely different things or if they're overlapping a lot. I understand the definition of a category, and Landau just made me aware of the definition of a structure yesterday. Other than that, I know close to nothing about these things.(adsbygoogle = window.adsbygoogle || []).push({});
