B.03 Paper at an international scientific conference
COBISS.SI-ID: 14443353Prof. Omladič regularly organizes a big linear algebra conference. In 2008 I organized special section on Real Algebra and its interactions with Functional Analysis, where around 25 international experts have participated, see e.g. http://www.law05.si/index.php?stran=special_RAFA
B.01 Organiser of a scientific meeting
Head of this postodoctoral research project (January 2007-December 2008). The goal of the project was to study notions of positivity in noncommutative real algebraic geometry.
D.01 Chairing over/coordinating (international and national) projects
Head of the bilateral cooperation project between Slovenia and France 2009-2010 within the Proteus program (the PI on the French side is M. Schweighofer).
