with Dr. Heer Zhao

We will study a series of topics which naturally continues those discussed in the lecture course Algebra 1 – Trace and Norm, Hilbert’s Theorem 90, Solvability of equations by radicals, infinite Galois theory, cyclotomic fields, the quadratic reciprocity law, simple cases of Fermat’s Last Theorem.

Prerequisites: Algebra 1 (Groups, Rings, Fields, Galois theory) and of course the basics (Linear Algebra 1 + 2, and maybe a bit of analysis).

Time and place: Tue, 14-16, S-U-3.03, First talk: April, 10.

Contact: ulrich.goertz@uni-due.de

ECTS points: 6 credit points for a successful seminar talk (in German or in English upon the choice of the speaker)

Program: pdf

Organisational meeting: February 15, 2:15pm, S-3.14. If you are interested in giving a talk in the seminar but cannot come to the organisational meeting, please send me an email.
