Update

I have now lectured until the middle op page 218 (Kleene's Normal Form Theorem). 

It is important to understand Kleene's theorem.  You should try to do the ex. 1, 2, 3 and 4 at page 223. You should also work with the exercises in Section 7.3.1 (exercise 8 and 9 are for the specially interested).

The next lecture will take place March 3 (so no lecture next week). Then, I will continue to lecture Section 7.4. Thereafter I will  lecture Section 7.5. Section 7.4 will be  lectured thoroughly. Section 7.5 will be lectured more superficially.
