In mathematics, algebraic spaces form a generalization of the schemes of algebraic geometry, introduced by Michael Artin [1] for use in deformation theory. Intuitively, schemes are given by gluing together affine schemes using the Zariski topology , while algebraic spaces are given by gluing together affine schemes using the finer étale topology .
Oct 9, 2017 · An algebraic space is a sheaf of sets $F$ in the étale topology of schemes satisfying the condition of local representability (in the étale topology): There exists a scheme $U$ and a sheaf morphism $\tilde U \rightarrow F$ such that for any scheme $V$ and morphism $\tilde V \rightarrow F$ the fibred product $\tilde U \times_F \tilde V$ is ...
In mathematics, a space is a set (sometimes known as a universe) endowed with a structure defining the relationships among the elements of the set. A subspace is a subset of the parent space which retains the same structure.
Nov 5, 2018 · An algebraic form, or simply form, is a function defined by a homogeneous polynomial. A form is also a function defined on a vector space, which may be expressed as a homogeneous function of the coordinates over any basis.

Algebraic topology also considers the global properties of spaces, and uses algebraic objects such as groups and rings to answer topological questions. Algebraic topology converts a topological problem into an algebraic problem that is hopefully easier to solve.
