Abstract. We investigate unilamellar membranes and vesicles composed of an
A/B mix-
ture of partially miscible amphiphiles. Assuming a
simple bilinear coupling between relative
composition and local curvature, and in the strong segregation limit of the A/B mixture, we
show for unilamellar open-shape membranes that the competition between sudace tension and
curvature results in a
phase with a
