Course Objective

The aim of this course is to introduce methods of commutative algebra with a view towards algebraic geometry and with the computational methods using Groebner basis.

Learning Outcomes of the Course Unit

1   Will be able to find Groebner basis of a given ideal in the polynomial ring over a field with n indeterminates.
2   Will be able to determine whether a given polynomial is in a given ideal in the polynomial ring over a field with n indeterminates using Groebner basis and division algorithm.
3   Will be able to solve a given system of polynomial equations over a field with n indeterminates under suitable conditions using the Elimination Theorem and the Extension Theorem.
4   Will be able to find the smallest variety containing a set defined by polynomial parametrizations by using the Elimination Theorem.
5   Will be able to interpret the relation between ideals and varieties using the ideal-variety correspondence and the Hilbert s Nullstellensatz when the field is algebraically closed.
6   Will be able to interpret the coordinate ring of an affine variety as a quotient ring of the polynomial ring.
