A point in a dynamical system's state space that maps back to itself.

A special trajectory of the dynamical system which does not change in time. It is also called an equilibrium, steady-state, or singular point of the system.

A projectile point permanently attached to its shaft, as opposed to a toggling head.

or defining point - a reproducible standard value, usually derived from a physical property of a pure substance. For example the triple point of pure water defines a temperature of 0.010°C

a point in phase space that the solutions never escape from

a point that a system evolves towards, such as the final states of a falling pebble, a damped pendulum, or the water in a glass

a point that does not change upon application of a map, system of differential equations, etc

a point which doesn't change under a given transformation

A very reproducible temperature at the equilibrium point between phase changes in a material. The triple point of water (0.01ºC) is an example of a fixed point.

The "fixed point" is an image volume of SectionView that determines the position of the section. The displayed section is defined by the viewing angles "pitch", "yaw" and "roll", the distance parameter and the position of the fixed point. Rotation is around the fixed point which can be interactively adjusted; by default, it is at the centre of the reference image bounding box.

A point in the upper dorsal spine which is considered as aligned to the vertical axis and about which longitudinal rotation of the cervical spine and the head take place as a unit when abnormally moving into either the right or left frontal plane.

In mathematics, a fixed point (sometimes shortened to fixpoint) of a function is a point that is mapped to itself by the function.
