The schedule of ICTS courses for **Jan - Apr 2017 **are** **given below:

**1. Classical fields - elasticity theory and fluid dynamics (Core)**

__ Instructor__: Abhishek Dhar

** TA : **Aritra Kundu

__ Prerequisites:__ Classical Mechanics

__ Summary__: The course will be based almost entirely on the book "Applications of classical physics" by Roger D. Blandford and Kip S. Thorne. The focus will be on explaining the basics of elasticity theory and fluid dynamics, and their applications to understanding various physical phenomena, both from everyday life and from the laboratory.

__ Course contents__: Chapters 11-15 of "Applications of classical physics" available in http://www.pmaweb.caltech.edu/Courses/ph136/yr2012/

__ Evaluation__: There will be two exams and around 6 assignments. Equal weightage will be given to the exam and assignments in the final grading.

__ NOTE__: First class will be at

**3:45 pm**on

**Wednesday, Jan 11, 2017**in Emmy Noether Seminar Room, ICTS Campus, Bangalore. Those interested in attending the course should send an email to abhishek.dhar@icts.res.in expressing their interest and mentioning if they would like to credit/audit the course.

**2. Data Assimilation and Dynamical Systems (Elective)**

** Instructor**: Amit Apte (ICTS-TIFR) and Somyendu Raha (CDS, IISc)

__ Course contents__:

- Quick intro (or recap) for nonlinear dynamics: bifurcations, unstable manifolds and attractors, Lyapunov exponents, sensitivity to initial conditions and concept of predictability.
- Markov chains, evolution of probabilities (Fokker-Planck equation), state estimation problems.
- An introduction to the problem of data assimilation (with examples)
