Events: Conference: Numerical Algebra, Matrix Theory, Differential-Algebraic Equations, and Control Theory

May 6th, 2015
This conference aims at bringing together experts in the fields of numerical (linear) algebra, matrix theory, differential-algebraic equations and control theory. The conference is dedicated to Volker Mehrmann, who is a leading expert in the areas of the conference, and in a unique manner unifies expertise in the mathematical fields providing the title of this conference, on the occasion of his 60th birthday.
