University of Iceland sets 20 November PhD defence on stability of switched systems
Stefanía Andersen Aradóttir will defend a mathematics doctorate on numerical Lyapunov function methods at the University of Iceland on 20 November 2026, with opponents from China and Georgia.
Why it matters: Stefanía Andersen Aradóttir and the University of Iceland's Faculty of Physical Sciences hold the doctoral examination on 20 November, before opponents from Beijing and Kutaisi.
The University of Iceland announced that Stefanía Andersen Aradóttir will defend her doctoral thesis in mathematics on 20 November 2026, from 09:00 to 11:00, in the Ceremonial Hall of the Main Building, with free admission.
According to the university, the thesis deals with stability analysis of linear switched systems through numerical computation of Lyapunov functions that are continuous and piecewise linear or piecewise quadratic, using linear optimisation.
The university said the opponents are Dr Shenyu Liu of the School of Automation at Beijing Institute of Technology and Dr Florian Rupp of Kutaisi International University in Georgia.
The supervisor is Professor Sigurður Hafstein of the Faculty of Physical Sciences, and the defence will be chaired by Professor Birgir Hrafnkelsson, head of that faculty, the announcement said.
