Redirect to:

This page is a redirect. The following categories are used to track and monitor this redirect:

From an avoided double redirect: This is a redirect from an alternative title or related topic of Null homotopy, another redirect to the same title. Because double redirects are disallowed, both pages currently point to Homotopy#null homotopic.
- If Null homotopy is retargeted or is expanded into a separate article, template, or other project page, this redirect will be recategorized to be updated.

From an alternative hyphenation: This is a redirect from a title with an alternative hyphenation of Null homotopic. Pages that link to this redirect may be updated to link directly to the target page if that results in an improvement of the text. Do not "fix" such links if they are not broken. Also, these links should not be replaced with piped links.

From an adjective: This is a redirect from an adjective, which is a word or phrase that describes a noun, to a related word or topic.

From a subtopic: This is a redirect from a subtopic of the target article or section.
- If the redirected subtopic could potentially have its own article in the future, then also tag the redirect with {{R with possibilities}} and {{R printworthy}}.

To an embedded anchor: This is a redirect from a topic that does not have its own page to an embedded anchor on the redirect's target page.
- An {{anchor|(anchor name)}} or {{visible anchor}} template, a HTML element with id="(anchor name)", or an |id=(anchor name) parameter might be installed at the beginning of a paragraph, in or near a section header or within a table. The anchor might also be an old section header that has been edited and is anchored within or near the new header to prevent broken internal and external links.
- Even though section headers of the general form ==(Header name)== are themselves a type of anchor, use {{R to section}} instead.

When appropriate, protection levels are automatically sensed, described and categorized.
