Applications in Hydrodynamic and Hydromagnetic Stability About the Book: This book is a monograph in the strict sense-homogeneous in point of view that may not always be the one that is commonly accepted and concerned with the frontier of research on some selected topics in hydrodynamic and hydromagnetic stability of the motion of viscous fluid with respect to infinitesimally small perturbations. Salient Features: 1. Chapter-1 is introductory in nature and concise the essential results in the respective fields of thermohaline convection, modified thermohaline convection (rotation and magnetic field). 2. Chapter-2 presents the bounds for complex wave velocity of an arbitrary mode in the instability problem of Veronis' and Stern thermohaline convection. 3. Chapter-3 deals with the modified thermohaline convection for the case of fluid completely confined in an arbitrary region with rigid bounding surface. 4. A further improvement of the results derived in Chapter-3 for the horizontal layer geometry are taken up in Chapter-4. 5. Chapter-5 extends the consideration of Chapter-4 to the rotatory modified magnetohydodynamic thermohaline convection.
