WebDiffeomorphic shapes are shapes that have maps between them that are, well, diffeomorphisms. Diffeomorphisms are a bit more complicated to define, but in essence those are maps that respect derivatives in some sense - this allows us to not pair only points, but also directions and velocities on their surfaces.

WebJan 1, 2008 · We describe a new class of surface flows, diffeomorphic surface flows, induced by restricting diffeomorphic flows of the ambient Euclidean space to a surface. Different from classical surface PDE flows such as mean curvature flow, diffeomorphic surface flows are solutions of integro-differential equations in a group of diffeomorphisms. In mathematics, a diffeomorphism is an isomorphism of smooth manifolds.
