Objective: 

This course will enable the students to –

  1. Test the importance of a ring as a fundamental object in algebra.
  2. Integrate the ideas about module and represents fundamental algebraic structures used in abstract algebra. 
  3. Create a module over a ring is a generalization of the notion of vector space over a field, wherein the corresponding scalars are the elements of an arbitrary given ring (with identity) and a multiplication (on the left and/or on the right) is defined between elements of the ring and elements of the module.
