• On–line Parameter and Delay Estimation of Continuous–Time Dynamic Systems

  Publikacja

  • Z. Kowalczuk
  • J. Kozłowski

  - International Journal of Applied Mathematics and Computer Science - Rok 2015

  The problem of on-line identification of non-stationary delay systems is considered. The dynamics of supervised industrial processes are usually modeled by ordinary differential equations. Discrete-time mechanizations of continuous-time process models are implemented with the use of dedicated finite-horizon integrating filters. Least-squares and instrumental variable procedures mechanized in recursive forms are applied for simultaneous...

• The equivariant spectral flow and bifurcation of periodic solutions of Hamiltonian systems

  Publikacja

  • M. Izydorek
  • J. Janczewska
  • N. Waterstraat

  - NONLINEAR ANALYSIS-THEORY METHODS & APPLICATIONS - Rok 2021

  We define a spectral flow for paths of selfadjoint Fredholm operators that are equivariant under the orthogonal action of a compact Lie group as an element of the representation ring of the latter. This G-equivariant spectral flow shares all common properties of the integer valued classical spectral flow, and it can be non-trivial even if the classical spectral flow vanishes. Our main theorem uses the G-equivariant spectral flow...
