This week, we'll have a talk by Alvyn Wiratama (abstract below) on complex and hypercomplex numbers. And, of course, free pizza!
Abstract: The complex number system is a neat application of how to use the square root of -1. However, there are other number systems that draw on the same basic ideas as the complex numbers, which we call Hypercomplex numbers. These number systems behave very differently compared to real or complex numbers, with some lacking expected algebraic properties such as associativity or commutativity. This talk will be an expansive overview about the complex and hypercomplex world of abstract algebra. No prior background in abstract algebra is required to listen and understand.
