53. Stability by linear approximation for time scale dynamical systemsSergey Kryzhevich, Alexander Nazarov, 2017, izvirni znanstveni članek Opis: We study systems on time scales that are generalizations of classical differential or difference equations and appear in numerical methods. In this paper we consider linear systems and their small nonlinear perturbations. In terms of time scales and of eigenvalues of matrices we formulate conditions, sufficient for stability by linear approximation. For non-periodic time scales we use techniques of central upper Lyapunov exponents (a common tool of the theory of linear ODEs) to study stability of solutions. Also, time scale versions of the famous Chetaev’s theorem on conditional instability are proved. In a nutshell, we have developed a completely new technique in order to demonstrate that methods of non-autonomous linear ODE theory may work for time-scale dynamics.

54. eastweetswest : :::::::: a performance process reflecting the state of unityPeter Purg, 2016, umetniško delo Opis: "After more than a quarter century thoughts and actions were shared, reflecting the state of unity. Ključne besede: " The Twitter account of grüntaler9 invited everyone to tweet/comment upon the topic of East & West. The performer arranged selected feeds, printed out on paper and cut to tile size onto the Black & White floor tiles of the space.
Performative (re)actions emerged by performer and participants, online and on site, critical or speculative, mythical or manipulative... Live feeds were used primarily, recycling material was an option. Text was used primarily, pictures are an option.
After more than a quarter century thoughts and actions were shared, reflecting the state of unity."
Live Performance 12 – 14h at grüntaler9, berlin, Germany
