Elements of Classical and Geometric Optimization

Debasish Roy, Professor, Department of Civil Engineering, Indian Institute of Science, Bangalore. He obtained his Ph.D. from the Indian Institute of Science, followed by post-doctoral research at the University of Innsbruck, Austria. He has published over 140 research papers in journals of national and international repute. His current research areas include geometrically inspired and gauge theories for continuum mechanics of solids, non-equilibrium thermodynamics of solids and fluctuation relations valid far from equilibrium, defect engineering and metamaterials with acoustic band gaps and optimization based on stochastic search on Riemannian manifolds. G. Visweswara Rao is currently working as an engineering consultant in Bangalore, India. He received his Ph.D. from the Indian Institute of Science, Bangalore, in 1989. He has published several research papers in the areas of structural dynamics specific to earthquake engineering, nonlinear and random vibration, and structural control. His areas of research include non-linear and stochastic structural dynamics.
