# Fibration

From Topospaces

*This article defines a property of continuous maps between topological spaces*

## Definition

A continuous map of topological spaces is termed a **fibration** or is said to have the **homotopy lifting property** if it is *surjective* and, given any map and a map such that , there exists a map satisfying:

This is dual to the notion of a cofibration.
