Vatsa B.S., Vatsa S. Discrete Mathematics

4th edition. — New Age International, 2009. — 315 p. — ISBN: 8122425747 , 8122425062The fourth edition retains all chapters of third edition and chapter 4: Ordered Sets and Lattices and chapter 10: Combinatorics as well as several sections on Set Theory, Boolean Algebra, Geometric Linear Transformation and Linear Equation are added. We have tried to emphasize that concept and terminology should be introduced before they are used.As such, it is useful in computer science, electrical engineering, mathematics, and professional courses also. Discrete mathematics is a pre-requisite in most computer programmes, MCA, M.Sc., B.Tech., B.Sc., BCA, BBA, PGDCA etc. of Indian Universities. A special care has been taken to make the concept of the subject and theorem on it clear by numerical illustrations so that the reader can go into the depth of the subject and make its application where they need.
