Late Prof. A. H. Siddiqi was an Indian Mathematician and Professor of Applied Mathematics. He was serving as Professor Emeritus in the School of Basic Sciences and Research at Sharda University, Greater Noida, India. He has also served as a Former Pro Vice-Chancellor, Aligarh Muslim University. Siddiqi was also the President of Indian Society of Industrial and Applied Mathematics (ISIAM). He has authored 12 books, edited 12 volumes and published more 100 research papers. He has also held important administrative positions in AMU and other institutions of repute. Dr. R. C. Singh has rich experience of more than 30 years as a researcher out of which more than 10 years as Professor of Physics. Presently, Dr. Singh is Professor of Physics and in addition to that he is also Controller of Examinations of Sharda University. Dr. Singh obtained his doctorate from Banaras Hindu University (BHU), Varanasi in theoretical Condensed Matter Physics. He obtained his B.Sc. (Hons.) and M.Sc. degrees also in Physics from Banaras Hindu University. Dr. Singh has published more than 30 research papers in peer-reviewed international journals and conference proceedings. He has authored one book and co-edited seven conference proceedings. His area of research interest includes study of phase transitions in molecular liquids using density-functional theory; Time-series analysis using wavelets; Biometrics and Solar cells. Dr. G. D. Veerappa Gowda is Professor at TIFR Centre for Applicable Mathematics, Bangalore. He has done fundamental work in the areas of Hyperbolic conservation laws, Control theory and Numerical approximation of conservation laws. Dr. Gowda obtained an explicit formula for the entropy weak solution of convex conservation laws with boundary conditions, extending the earlier work of Hopf and Lax for the initial value problem. Dr. Gowda has developed numerical schemes to solve problems arising in oil recovery and sand pile problem on a vertical source.
