Notes
Part II : Ideals, varieties and algorithms 
Main topics: 
(i)     Groebner basis basics orderings on
monomials 
  - Division algorithm in the polynomial ring
 
- Monomials Ideals and Dickson’s lemma
- Hilbert Basis Theorem and Groebner Basis
- Buchberger’s algorithm 
- Ideal membership problem, implication problem and elimination
theory
