What is Inverse image functor?

In mathematics, the inverse scattering transform is a method for solving some non-linear partial differential equations. The method is a non-linear analogue, and in some sense generalization, of the Fourier...

In mathematics, particularly category theory, a representable functor is a certain functor from an arbitrary category into the category of sets. Such functors give representations of an abstract category in...

In abstract algebra, the set of all partial bijections on a set X forms an inverse semigroup, called the symmetric inverse semigroup on X. The conventional notation for the symmetric...

In algebra, a polynomial functor is an endofunctor on the category...

In category theory, a branch of mathematics, a conservative functor is a functor F :...

In mathematics, certain functors may be derived to obtain other functors closely related to the original ones. This operation, while fairly abstract, unifies a number of constructions throughout mathematics.

In mathematics, specifically in category theory, a functor is essentially surjective if each object d...

In mathematics, particularly homological algebra, an exact functor is a functor that preserves short exact sequences. Exact functors are convenient for algebraic calculations because they can be directly applied to...

In differential topology, a branch of mathematics, a smooth functor is a type of functor defined on finite-dimensional real vector spaces. Intuitively, a smooth functor is smooth in the sense...

Inverse vulcanization is a solvent-free copolymerization process that produces polymers containing chains of sulfur atoms. This process exploits the wide availability of high purity sulfur, a by-product from the crude...
