Outline of Final Research Achievements |
(1) We succeeded to obtain a new relation between a Wulff shape, which are known as the geometric model of a crystal at equilibrium, and the perspective projection by using Singularity Theory of Smooth Mappings. (2) In the last half of this research period, from various viewpoint we studied close relationships between a Wulff shape and its convex integrand which is the best efficient continuous function generating the Wulff shape. We have obtained many results on these topics. As of the beginning of June 2016, these results are still under submission.
