Riemann Integration and Series of Functions

By Sanjay P. K.   |   National Institute of Technology, Calicut
Learners enrolled: 648
The course "Riemann Integration and Series of Functions" is proposed for B.Sc Mathematics or B.Sc. (Hons) Mathematics students. The course content is divided in to 39 modules and the course credit is four. The first part of the course discusses Riemann's theory of integration. It starts with the definition of the Riemann sum, which naturally leads to the notion of integrals, discusses equivalent conditions for the existence of integral and properties of integral and finally proves the 'Fundamental Theorem of Calculus'. The second part of the course is on the sequence and series of functions, where we will look at the significance of 'uniform convergence' to prove the continuity, differentiability and integrability of the limit function of a sequence of functions. Finally, we will define limit superior and limit inferior and discuss results for the special case of 'power series'.
