Abstract: In this paper, we investigate some properties of planar soap
bubbles on a straight wall with a single corner. We show that when a wall has a single
corner and a bubble consists of two connected regions, the perimeter minimizing bubble
must be one of the types, two concentric circular arcs or a truncated standard double
bubble, depending on the angle of the corner and areas of the regions.
