Abstract
The shape of a liquid surface bounded by an acute or obtuse wedge is considered by using classical analysis methods. For acute wedges the two principal curvatures are of the order of the (fixed) mean curvature. But for obtuse wedges, the principal curvatures both diverge as the vertex is approached. The power-law divergence becomes stronger with increasing opening angle. Possible implications of this contrasting behavior are suggested.
