Abstract

In this short note, we present several ideas and observations concerning finite element convergence and the role of the maximum angle condition. Based on previous work, we formulate a hypothesis concerning a necessary condition for O(h) convergence and show a simple relation to classical problems in measure theory and differential geometry which could lead to new insights in the area.
