Analytic set

Not to be confused with Analytical set.
For analytic sets in geometry, see analytic space.

In the mathematical field of descriptive set theory, a subset of a Polish space is an analytic set if it is a continuous image of a Polish space. These sets were first defined by Luzin (1917) and his student Souslin (1917).[1]
