In this post we discuss local class field theory (specifically lookingÂ at -adic fields) with a focus on the broader picture, and the multiple approaches.

# A computation a day: the Brauer group of a number ring

In this post we compute the group where is a number field.

# A class field theoretic phenomenon

In this post we discuss one example of what’s called a ‘class field theoretic phenomenon’. In particular, we focus on the application of trying to understand the property of when has three distinct roots modulo , for various primes .
