September 6-7

This week, I started with the proof of Proposition 2.5 and completed the week by stating Proposition 2.27. Also I had time to solve Exercise 2.2. I followed book closely. Next week, tentative program is completing Section 2.5 by proving Proposition 2.28 and I will give some definitions from Section 2.6. Then, I will start Chapter 3 and hope to reach to end of Theorem 3.4. Planned exercises are Exercises 2.4, 2.7, 2.16, 2.17 and 2.21.
