After studying Theory of Numbers, Class Field Theory deals with abelian extensions of local fields and global fields with various arithmetic properties of the abelian extensions. To prove Artin-Verdier Duality, many subareas of algebraic number theory, Class-Field-Theory is used where this [course_title] will help you understand effectively. This [course_title] will provide you with Quadratic extensions and Hilbert symbols, Homological algebra, Galois Cohomology etc. in details to meet your needs.


This course does not involve any written exams. Students need to answer 5 assignment questions to complete the course, the answers will be in the form of written work in pdf or word. Students can write the answers in their own time. Each answer needs to be 200 words (1 Page). Once the answers are submitted, the tutor will check and assess the work.


Edukite courses are free to study. To successfully complete a course you must submit all the assignment of the course as part of the assessment. Upon successful completion of a course, you can choose to make your achievement formal by obtaining your Certificate at a cost of £49.

Having an Official Edukite Certification is a great way to celebrate and share your success. You can:

  • Add the certificate to your CV or resume and brighten up your career
  • Show it to prove your success
