ADVANCED TOPICS IN FLUID DYNAMICS (Hydrodynamic Stability) (Fall 2013)

MATH-GA 2861.003 ADVANCED TOPICS IN FLUID DYNAMICS (Hydrodynamic Stability) 3 points. Fall term. Monday, 9:00-10:50, N. Masmoudi.

Prerequisite: some background in PDE. The course will be mostly about stability and instability results for 2D Euler. It will be a mixture of rigorous proofs and of some formal arguments. We will discuss in particular : (1) the Rayleigh criterion and its generalizations; (2) the Orr-Sommerfeld equation; (3) Different notions of stability and instability; (4) some boundary layers. Grading: this course will be graded as a seminar course.
The first class will be on Monday September 9th.

The plan is to cover :
I) Classical existence results about Euler system.
II) Classical stability results including the Rayleigh criterion and its generalizations
III) Some boundary layers
