This page contains information about the course MA6201E Real analysis that I will be teaching in the semester July - November 2024 in NIT Calicut for the 1st year M. Sc (Mathematics) students.
MA6201E should technically be a second course in real analysis. We assume that you have done a first course in real analysis and you know the following topics:
sequences/series of real numbers, their convergence
"real valued"continuous, differentiable, integrable functions
You may visit https://sites.google.com/view/praphulla-koushik/mt2223-real-analysis-i to get some idea of what is assumed in this course.
Nevertheless, we will recall all those ideas with a n-times speed of how you might have learnt it in the first course (for n anywhere between 1 and 10). This should take around 2 weeks.
The new things will start from the notion of sequence/series of real valued functions (topic 24 mentioned below)
