Particularly topologically interesting classes of maps include embeddings, immersions, and submersions. Geometrically interesting are isometries and isometric immersions. It follows that immersed submanifolds are precisely the images of injective immersions. More generally, minimal submanifolds are harmonic immersions of one manifold in another. Note, however, that the converse is false&colon; there are injective immersions that are not embeddings. One can study embeddings as "immersions without multiple points", since immersions are easier to classify. A regular homotopy is thus a homotopy through immersions. Cross-disciplinary immersions are encouraged at ICTS. The homotopy must be a 1-parameter family of immersions. The Hirsch-Smale classification of immersions was generalized by Mikhail Gromov. For medically prescribed bathing the standard dip was apparently three total immersions. It also studies immersions of graphs. A graph operation called "lifting" is central in a concept called "immersions". Other non-avalanche snow immersions can be similarly dangerous, including tree wells. MBA@Denver offers students multiple concentration options, leadership immersions, and a capstone project.
