IST PDE : Theory and Computation (2018) - Speakers and Syllabus

PDEs arise naturally in many mathematical modelling describing physical phenomenon and engineering applications. It is therefore important to understand the PDEs and their solution process. The theory of PDEs consists of studying the existence, uniqueness of the solution and further to establish its stability and regularity. The solution process includes to develop methodologies to find solutions either in closed form or by an approximation. The instructional school aims to provide the participants a tour to classical theory of second order PDEs and to introduce to them the advanced PDEs through variational approach. Furthermore, the school aims to demonstrate numerical analysis and techniques to solve the PDEs, in particular, finite difference methods and finite element methods . The topics in the school are designed in such way that the participants get exposure to topics in both classical and modern approach in the theory and computation of PDEs which are also part of the curriculum in the universities and post graduate colleges.
