Additional Notes:
COMMENT: I taught 221AB from this book in 2007-2008 and appreciated the clarity, readability and variety of interesting topics covered in the book. Cohen & Kundu also has a lot more material than one can cover in a two-quarter course. It is, however, not written in the style of a typical "mathematical fluids" book. For the latter, one can consult, e.g., the well written Mathematical Theory of Incompressible Nonviscous Fluids by Marchioro and Pulvirenti. Such books are often more focused but limited in scope.
