Introduction to Commutative Algebra

Introduction to Commutative Algebra. Instructor: Prof. A. V. Jayanthan, Department of Mathematics, IIT Madras. This is an introductory course in Commutative Algebra where most basic tools on commutative rings and modules over commutative rings are developed. This course is essential for anyone who wants to do research in areas such as commutative algebra, algebraic geometry, algebraic number theory etc. (from nptel.ac.in)
