Minimizing energy

Schnappschüsse moderner Mathematik aus Oberwolfach

Minimizing energy

What is the most efficient way to fence land when you’ve only got so many metres of fence? Or, to put it differently, what is the largest area bounded by a simple closed planar curve of fixed length?
We consider the answer to this question and others like it, making note of recent results in the same spirit.
