Objective: 

This course will enable the students to –

  1. Understand the importance of a ring as a fundamental object in algebra.
  2. It also gives ideas about module and represents fundamental algebraic structures used in abstract algebra. 
  3. Understand 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.

Modules and Rings-I

   (Theory)

 

 

 

 

The students will be able to –

 

CO128: Get an introduction to module theory and the related part of ring theory starting from a basic understanding of linear Class Tests at Periodic algebra.

CO129: Describe the types of modules.

CO130: Understand the structure theory of modules over a Euclidean domain along with its implications.

CO131: Know about Divisible groups, Jordon-Holder theorem, Indecomposable modules, Krull–Schmidt theorem, images and direct sum of semi-simple modules.

CO132: Identify Prime ideals, m-system, Prime radical of an ideal, Prime radical of a ring, Semiprime ideal, n-system.

CO133: The material underpins many later courses in algebra and number theory, and thus should give students a good background for studying these more advanced topics.
