Inclusion map

In mathematics, if is a subset of then the inclusion map (also inclusion function, insertion, or canonical injection) is the function that sends each element of to treated as an element of A "hooked arrow" (U+21AA ↪ RIGHTWARDS ARROW WITH HOOK) is sometimes used in place of the function arrow above to denote an inclusion map; thus: (However, some authors use this hooked arrow for any embedding.) This and other analogous injective functions from substructures are sometimes called natural injections. Given any morphism between objects and , if there is an inclusion map into the domain then one can form the restriction of In many instances, one can also construct a canonical inclusion into the codomain known as the range of (Wikipedia).

Stable Homotopy Seminar, 2: Fiber and Cofiber Sequences

We review some unstable homotopy theory, especially the construction of fiber and cofiber sequences of spaces, and how they induce long exact sequences on homotopy and homology/cohomology. (There's a mistake pointed out by Jeff Carlson: when I take a CW-approximation at one point, I have

Intuitive Persistence This lecture introduces the persistent homology of a filtration of a simplicial complex. In each dimension inclusions of the filtration subcomplexes induce a sequence of maps on the homology vector spaces of the given dimension of the subcomplexes. Tracking cycles fr

Jintian Zhu - Incompressible hypersurface, positive scalar curvature and positive mass theorem

In this talk, I will introduce a positive mass theorem for asymptotically flat manifolds with fibers (like ALF and ALG manifolds) under an additional but necessary incompressible condition. I will also make a discussion on its connection with surgery theory as well as quasi-local mass and

Lecture 5: The definition of a topos (Part 2)

A topos is a Cartesian closed category with all finite limits and a subobject classifier. In his two seminar talks (of which this is the second) James Clift will explain all of these terms in detail. In his first talk he defined products, pullbacks, general limits, and exponentials and in
