Differential Equations and Numerical Analysis

Valarmathi Sigamani is assistant professor at the Department of Mathematics at Bishop Heber College, Tiruchirappalli, Tamil Nadu, India. She did her doctoral studies in numerical analysis at Bharathidasan University, Tiruchirappalli, under the guidance of Prof. N. Ramanujam. She has been teaching algebra, analysis, topology, calculus of variations, computer programming and differential equations to undergraduate and postgraduate students of mathematics. She has published 20 research articles in various reputed international journals and has guided 5 students and guiding some more in their doctoral studies in singular perturbation problems and numerical analysis. Currently, she is working on the qualitative and quantitative analysis of singularly perturbed multi-scale dynamical systems and their applications in biology. She is a council member of the Institute of Numerical Computation and Analysis (INCA), Dublin, Ireland, and is a member in various mathematical societies. John J.H. Miller is director of the Institute for Numerical Computation and Analysis (INCA), Dublin, and professor emeritus of mathematics at the Trinity College, Dublin. He obtained two undergraduate degrees at Trinity College, University of Dublin, Ireland: one in mathematics and the other in natural sciences. He then studied numerical analysis at the Massachusetts Institute of Technology under the supervision of Gilbert Strang, where he was awarded a PhD degree. His mathematical interests include power bounded matrices, the zeros of polynomials, numerical methods for modelling semiconductor devices, asymptotic and computational methods for problems exhibiting boundary and interior layers, data analysis of signals from neurons and, recently, the mathematical modelling and construction of oscillating water column devices for generating electric power from ocean waves. He has written over 100 papers on these topics, as well as 3 research monographs. Ramanujam Narasimhan is an honorary professor of mathematics at Bharathidasan University, Tiruchirappalli, Tamil Nadu. He worked under the guidance of Dr. U.N. Srivastava and got his PhD degree from the Indian Institute of Technology Madras. His research interests include differential equations and numerical analysis. He has published over 85 papers in various international journals and has guided 11 students in their doctoral studies. He has been teaching various courses such as ordinary differential equations, partial differential equations, numerical analysis, functional analysis, fluid dynamics, computer programming, real analysis, integral equations and calculus of variations. He has served in many responsible positions including the vice-chanceller (in-charge) of Bharathidasan University. Paramasivam Mathiyazhagan is assistant professor of mathematics at Bishop Heber College, Tiruchirappalli, Tamil Naud. He got his PhD from BharathidasanUniversity in 2013. His research interests include numerical analysis and boundary layer theory. He has worked on the multi-scale reaction-diffusion problems and has published articles in reputed international journals. He has been teaching various courses such as partial differential equations, functional analysis, fluid dynamics and computer programming. Apart from mathematics, he is a brilliant cricketer who played for the university during his college days. Franklin Victor is assistant professor of mathematics at Bishop Heber College, Tiruchirapalli, Tamil Nadu. He completed his doctoral studies in numerical methods for solving singularly perturbed partial differential equations of parabolic type. Recently, he got interest in delay differential equations and is currently working on numerical methods to solve singularly perturbed delay differential equations. His other research interests are mathematics of finance and Black-Scholes equations. He has been teaching various courses such as mathematical analysis, ordinary differential equations and partial differential equations. Besides mathematics, he is a talented musician. He is a reputed choral arranger and a conductor of various ensembles of his region.
