The shortest enclosure of three connected areas in \(\mathbb{R}^ 2\)
In the present paper the authors prove that the ``standard triple bubble'' is the shortest way to enclose and separate three areas \(A_ 1\), \(A_ 2\), \(A_ 3\) in \(\mathbb{R}^ 2\), assuming that the enclosed regions and the exterior region are connected.
