Constructive Analysis of Partial Differential Equations
This thesis presents the results produced in the study of weak solutions of the Dirichlet Problem within Errett Bishop's constructive mathematics. It roughly falls into three major parts: a critical analysis of the classical approaches from a constructive point of view (Chapter 2); constructive …

Combat modelling with partial differential equations
… of this thesis we extend the Lanchester Ordinary Differential Equations and construct a new physically meaningful set of partial differential equations with the aim of more realistically representing soldier dynamics in order to enable a deeper understanding of the nature of conflict. Spatial …

Variational Methods for Nonlinear Partial Differential Equations
… methods for solving a class of nonlinear partial differential equations. First, relevant mathematical background of functional analysis and variational calculus is explained. One of the main results discussed is the existence theorem for minimizer of functionals for the case of fixed …

Model Predictive Control for Partial Differential Equations
… concerned with model predictive control (MPC) of partial differential equations. The idea is to approximate an infinite time horizon optimal control problem by a sequence of finite horizon optimal control problems. The optimization horizon plays a crucial role in the stability analysis. In the …

Approximation of random/stochastic partial differential equations
… of this thesis lies in approximations of partial differential equations (PDEs) with randomness or stochasticity. We focus on three rather different problems: a study of random fields on spherical shells, and its applications to PDE problems; quasi-Monte Carlo (QMC) methods for a class of …

Physics motivated algorithms for partial differential equations
… and the most popular means to model them is the partial differential equation (PDE). Resultant PDEs are, however, often nonlinear, defying analytical approaches. Thus, devising efficient numerical algorithms to solve PDEs is important for the study of nonequilibrium systems, and has traditionally …

Preconditioning techniques for stochastic partial differential equations
… techniques for time dependent stochastic Partial Differential Equations arising in the broader context of Uncertainty Quantification. State-of-the-art methods for an efficient integration of stochastic PDEs require the solution field to lie on a low dimensional linear manifold. In cases …

Self Adaptive Methods for Parabolic Partial Differential Equations
In many applications, the solutions to important partial differential equations are characterized by a sharp active region of transition (such as wave fronts or areas of rapid diffusion) surrounded by relatively calm stable regions. The numerical approximation to such a solution is based on a mesh …
