Real Analysis: Course Contents (MAT 409)

Real analysis (traditionally, the theory of functions of a real variable) is a branch of mathematical analysis dealing with the real numbers and real-valued functions of a real variable.

Course Objective

At the end of this course the students will be able to review elementary mathematics from an advanced standpoint, insight into the role of rigor in mathematics. Build understanding of the foundations and concepts of analysis and strengthen powers of logic (reasoning). Define Riemann integral and Riemann sums, prove various theorems about Riemann sums and Riemann integrals and emphasize the proofs’ development. Define uniform convergence and prove their theorems. Study and apply Fourier series theorems (e.g convergence criteria etc.)
