Abstract
We discuss a theoretical model for a surface transition in a nonspheri cal geometry. We study the stationary states of coexistence within a d roplet of given volume. We show that finite range interactions with th e matrix act to stabilize a finite non-spherical surface layer which i s thickest in zones of highest curvature. At a certain temperature, th e core tends to a spherical shape, becomes unstable and coexistence is no longer possible.
