Brouwer fixed point theorem in strictly star-shaped sets
Keywords:
Brouwer fixed point, Star-shaped, retraction, contractible, homotopy groupsAbstract
In this note, we show that the Brouwer fixed point theorem in open strictly star-shaped sets is equivalent to a number of results closely related to the Euclidean spaces.References
