## homotopyHomotopy is a continuous transformation from one path in a topological space to another, or, more generally, of one function to another. Paths connected by a homotopy are called homotopic and are said to be in
the same homotopy class. Properties left unchanged by such
homotopies are known as homotopy invariants. Homotopy classes
of paths can be composed to form the fundamental
group, or first homotopy group. Other maps can be used
to form higher homotopy groups. ## Related category• TOPOLOGY | |||||
