2   Will be able to understand the notion of flatness and related concepts.
3   Will be able to use the algorithms in computational commutative algebra that has been developed using Groebner basis.
4   Will be able to use the properties of graded rings, Cohen-Macaulay rings, regular local rings and Gorenstein rings.
5   Will be able to understand the notion of completion and the structure of complete local rings.
