A Basic Course in Real Analysis

A Basic Course in Real Analysis. Instructor: Prof. P.D. Srivastava, Department of Mathematics, IIT Kharagpur. This is an introductory course in real analysis, covering topics: the Dedekind theory of irrational numbers; the Cantor theory of irrational numbers; bounded set and the open, closed and compact, etcetera; continuity of the function; differentiability; the Riemann integration and Riemann stieltjes integral; and the improper integral.
