SUMMARY:Mini-workshop: Analysis, Numerics and Control
DESCRIPTION:Next Friday, May 26, 2023:\nEvent: FAU DCN-AvH Mini-workshop: Analysis, Numerics and Control\nOrganized by: FAU DCN-AvH, Chair for Dynamics, Control, Machine Learning and Numerics – Alexander von Humboldt Professorship at FAU, Friedrich-Alexander-Universität Erlangen-Nürnberg (Germany)\n14:00H\nTitle: Convex functions and its applications\nSpeaker: Prof. Dr. Çetin Yildiz\nAffiliation: Visiting Scientist at FAU DCN-AvH from Atatürk University, Turkey\nAbstract. The theory of inequalities has been the focus of researchers in the last decade. One of the main reasons for this interest is the definition of convexity. This definition firstly has appeared in Jensen’s (the celebrated Danish mathematician) papers in 1905. The convex functions has experienced a rapid development because the convex functions are closely related to the theory of inequalities and many important inequalities (such as Hermite-Hadamard inequality, Minkowski inequality, Jensen inequality) are consequences of the applications of convex functions.\nThe definition of the convex function can be represented as follows:\nDefinition: A function f: mathcal{I} subset mathbb{R} rightarrow mathbb{R}  is said to be convex if\n\nf (ta + (1-t)b) leq tf(a) + (1-t)f(b) \nholds for all a,b in mathcal{I}  and t in [0,1].\nThe Hermite-Hadamard inequality, which is the main result of convex functions’ widespread application and excellent geometrical interpretation, has received a lot of attention in fundamental mathematics. Recent years have seen a rapid development in the theory of inequality. Important inequalities, such as the Hermite-Hadamard inequality, are one of the most important reasons for this development. It is worth reflecting on the fact that the theories of inequality and convexity are closely related to one another. In recent years, several new extensions, generalizations, and definitions of novel convexity have been given, and parallel developments in the theory of convexity inequality, particularly integral inequalities theory, have been emphasized.\nInequalities involving fractional integrals are a special focus of the calculus of non-integer order, widely known as Fractional Calculus. This subject deals with the generalization of integrals and derivative operators. In the literature, there are several definitions for fractional integral operators, such as Hadamard integral, Riemann-Liouville fractional integral, Caputo-Fabrizio fractional integral, Riemann-Liouville fractional integral, and conformable fractional integral.\nIn this presentation, we aim to explain convex functions and important inequalities.\n \n14:30H\nTitle: Optimal control problems for multi-species diffusion-reaction equations in a porous medium\nSpeaker: Prof. Dr. Hari Mahato\nAffiliation: Visiting Scientist at FAU DCN-AvH from IIT Kharagpur.\nAbstract. We present an optimal control problem associated to a chemical transportation phenomena in a periodic porous medium. Our control problem consists of a L^2-cost (objective) functional which is a function of the control (input) and the state variables and subject to a set of constraints (diffusion-reaction-precipitation model). Posing controls on the porous part of the medium,  we set up a convex minimization problem to characterize an arbitrary control to be an optimal control. We first obtain the existence of solution of both state-equations (diffusion-reaction model) and optimal control. Then, we resolve a relation between optimal control and  solution of adjoint state of state-equations. Later, we do homogenization (upscaling) of the optimal control problem via. rigorous two-scale convergence and periodic unfolding method.\nWHERE?\nOn-site / Online\nOn-site:\nRoom Übung 4.
