Abstract: The motivation of this paper is the development of an optimisation method for solving optimisation problems appearing in Chebyshev rational and generalised rational approximation problems, where the approximations are constructed as ratios of linear forms (linear combination of basis functions). The coefficients of the linear forms are subject to optimisation and the basis functions are continuous function. It is known that the objective functions in generalised rational approximation problems are quasi-convex. In this paper we also prove a stronger result, the objective functions are pseudo-convex. Then we develop numerical methods, that are efficient for a wide range of pseudo-convex functions and test them on generalised rational approximation problems.

Seminars

Dynamic Control and Optimization conference, 3-5 February 2021, Aveiro, Portugal

The Dynamic Control and Optimization International Conference 2021 (DCO 2021) will take place at University of Aveiro, Campus of Santiago, from 3 to 5 February, 2021 (Wednesday-Friday). The conference is dedicated to the 65th birthday of Andrey V. Sarychev, Professor in University of Aveiro until 2002.

For more information please visit the conference site https://sites.google.com/view/dco2021/.

The conference is organized by the Department of Mathematics of the University of Aveiro, the Center for Research & Development in Mathematics and Applications (CIDMA, University of Aveiro) and the Center for Applied Mathematics and Economics (CEMAPRE, University of Lisbon).

Aims and Scope

  • nonlinear dynamical control systems,
  • control of evolution PDE,
  • optimal control,
  • sub-Riemannian geometry,
  • ordinary differential equations,
  • calculus of variations,
  • differential equations,
  • propagation of acoustic waves in elastic media.

The conference will consist of invited plenary talks (40 minutes + 5 minutes of q&a) and contributed paper presentations (20 minutes + 5 minutes of q&a).

Selected full papers of this conference will be published in an international journal.

Due to the COVID-19 situation and the possible lockdown, the conference is planned to be held in two simultaneous ways:

  • attended at the University of Aveiro, Aveiro, Portugal;
  • virtually using Zoom

To ensure that all conference attendees have access to all sessions, it is planned to transmit the sessions online or provide access to their recordings.

Regardless of how we handle the conference, we want to assure everyone that there will be a forum for contributors to share their work and participants to learn and network.
