AIS  on Stochastic Processes (2018)

Advanced instructional school on Stochastic Processes will be organized at NISER, Bhubaneswar sponsored by National Centre for Mathematics and Indian Academy of Sciences during 25th June to 21st July 2018.

Aims and Objectives: Most Indian Universities do not have a rigorous study on probability. The aim of this school is to give a comprehensive training to students in a master’s degree/PhD programme on probability and stochastic processes. Also to give them a chance to interact with researchers
in these topics.

We propose to run three courses in parallel

  1. Analysis,
  2. Measure-theoretic probability
  3. An introductory course on stochastic processes.

There will be around 36 hours of lectures including tutorials per topic over a 4 week period. In addition, over two weekends we plan to invite active researchers in probability to present introductory lectures on a research topic and interact with students.

    Students of Master/Ph.D. in Mathematics, Physics, Statistics, Computer Science and Electrical Engineering;
    B.Tech./M.Tech. (in CS and EE) and M.Phill (in Physics, Mathematics, Statistics)
How to Apply:

    Application can be made through either of the following websites on/before 01st May 2018.


    Around 40 students will be selected from the applications received and chosen on the basis of the student's background, educational qualifications and an assessment as to the extent to which the candidate would benefit from the programme. 
    Travel, local conveniences and course materials will be provided to the participants.

We plan to cover the following topics in this AIS. The proposal is a bit ambitious and we will tune it according to the level of students. Our aim is also to have a follow-up workshop later where selected students from this group will be introduced to more advanced topics.

  1. Analysis:Metric spaces, open/closed sets, sequences, compactness, completeness, continuous functions and homeomorphisms, connectedness, product spaces, Baire category theorem, completeness of C[0, 1] and L p spaces, Arzela-Ascoli theorem Analytic functions, Cauchy-Riemann equations, polynomials, exponential and trigonometric functions Contour integration, Power series representation of analytic functions, Liouville’s theorem,Cauchy integral formula, Cauchy’s theorem, Morera’s theorem, Cauchy-Goursat theorem Singularities, Laurent Series expansion, Cauchy residue formula, residue calculus. Meromorphic functions, Rouche’s theorem.Fractional linear transformations.
