Consider an orientable compact surface in three dimensional Euclidean spacewith minimum total absolute curvature. If the Gaussian curvature changes signto finite order and satisfies a nondegeneracy condition along closed asymptoticcurves, we show that any other isometric surface differs by at most a Euclideanmotion.
