1. Commutative Algebra : pdf
2. Lie Theory (İstanbul Lectures)
These lecture notes are based on the material that I learned from the books of Borel, Helgason, Knapp, Humphreys, Bernstein, Fulton and Harris.. If you read my notes carefully you will notice a lot of typos (of course, all due to me). Occasionally I am revising these notes, so, hopefully I will manage to get rid of all of the mistakes in a near future.
