This book is intended for seniors graduate students and research scholars. It is a self contained and covers the topics usually thought at this level. Starting we will discuss about the Indian legendary mathematician Sri Srinivasa Ramanujan Garu and next we will discuss about the main content of the book.Particularly this book divided into six chapters, in chapter 1 take as a introduction likely some basic definitions of this content, in second chapter we will discuss about the concept on Commutativity of semiprime rings with some identities, this divides into four parts first part is  On Commutativity of non Associative rings second part On commutativity of Associative rings third part Some results on the commutativity of accessible rings and fourth part is Some results on the commutativity of Associative rings.

 In chapter 3 we discuss about the concept On commutativity of primitive rings with some identities. Particularly in this first, second and third parts is On commutativity of non associative primitive rings with someidentities.    
In chapter 4 we will discuss about the properties On Commutativity of Periodic Rings.In first part we're discussed about some commutativity results for periodic rings, in second part we discuss about weekly periodic Rings with condition on commutators, In third part  we say about some commutativity Theorems On certain Rings and in third part we mentioned on Commutativity of rings with additional conditions
       
In chapter 5 we will discuss about Commutativity of S-unital rings and periodic rings. Particularly in this we will discuss some identities in the S-unital rings and periodic rings
            
Finally in chapter 6  we will discuss about the Problems for further study. Particularly how we can produce On Commutativity of prime rings with derivation, structure of periodic D-rings and weekly periodic D-rings, On Commutativity of generalised quasi-periodic rings.
