In the past few years sustainability and sustainable development have become important concepts widespread over the world. There is no agreement on a common definition of sustainability, but there is a general need to measure and assess sustainability in different geographical and spatial...

Causal inference in the empirical sciences is based on counterfactuals. This paper presents the counterfactual account of causation in terms of Lewis's possible-world semantics, and reformulates the statistical potential outcome framework and its underlying assumptions using counterfactual...

A classic paper of Borwein/Lewis (1991) studies optimisation problems over L^p_+ with finitely many linear equality constraints, given by scalar products with functions from L^q. One key result shows that if some x in L^p_+ satisfies the constraints and if the constraint functions are...

Seit ihrer Erkenntnis und Formulierung im Rahmen der Ausarbeitung der Thermodynamik zeigte sich, dass der Geltungsbereich der sog. Hauptsätze weit über die Grenzen der Thermodynamik im engeren Sinne herausreicht – sie sind offenbar das Fundament aller materiellen Prozesse. Unverständlich...
