二、Content and Schedule

In this series of lectures, we will discuss several topics related with the modeling, analysis, numerical simulation and control of non-local differential equations (NLDE)  arising in various areas of science and technology.

This course will be structured in 5 parts: 

PART I: Introduction to control theory. We will give a short introduction to control theory for ODE and PDE, presenting the notion of controllability and its dual version, the so-called observability problem.

PART II: Fractional in time models. We will discuss non-local in time models and their control properties. We will start by presenting ODE and PDE with memory, and introducing the moving control strategy to obtain the controllability of such systems. Later on, we will consider fractional-in-time ODE and PDE.

PART III: Fractional in space models. We will discuss non-local in space models and their control properties. We will start by presenting the fractional Laplace operator and its employment in PDE. Later on, we will analyze the controllability problem for this class of models.

PART IV: Numerical approximation of PDE and numerical control. We will discuss the numerical approximation of (local and non-local) PDE through finite difference and finite element methods. Secondly, we will address the numerical approximation of controls for local and non-local PDE, relating the controllability property to optimal control theory and optimization.

PART V: Complementary topics. We will discuss a couple of complementary topics related with the contents of this course: the so-called turnpike property, and PDE with non-local integral kernels.
