# Dendrite (mathematics)

In mathematics, a dendrite is a certain type of topological space that may be characterized either as a locally connected dendroid or equivalently as a locally connected continuum that contains no simple closed curves.[1]

Dendrite Julia set

## Importance

Dendrites may be used to model certain types of Julia set.[2] For example, if 0 is pre-periodic, but not periodic, under the function ${\displaystyle f(z)=z^{2}+c}$, then the Julia set of ${\displaystyle f}$ is a dendrite.[3]
