The research, processing, evolution, optimization and/or legislation, and keep watch over of shapes and pictures look obviously in engineering (shape optimization, photo processing, visible control), numerical research (interval analysis), physics (front propagation), organic morphogenesis, inhabitants dynamics (migrations), and dynamic financial theory.  

These difficulties are at the moment studied with instruments cast out of differential geometry and useful research, hence requiring shapes and photographs to be smooth.  notwithstanding, shapes and photographs are primarily units, pretty much no longer smooth.  J.-P. Aubin therefore constructs one other imaginative and prescient, the place shapes and pictures are only any compact set.  consequently their evolution -- which calls for a type of differential calculus -- needs to be studied within the metric area of compact subsets.  regardless of the lack of linearity, it is easy to move lots of the uncomplicated result of differential calculus and differential equations in vector areas to mutational calculus and mutational equations in any mutational area, together with evidently the gap of nonempty compact subsets.  

"Mutational and Morphological research" bargains a constitution that embraces and integrates many of the methods, together with form optimization and mathematical morphology.  

Scientists and graduate scholars will locate the following different robust mathematical instruments for learning difficulties facing shapes and pictures bobbing up in such a lot of fields.
