Hairy ball problem
Did you know?
A consequence of the hairy ball theorem is that any continuous function that maps an even-dimensional sphere into itself has either a fixed point or a point that maps onto its own antipodal point. This can be seen by transforming the function into a tangential vector field as follows. Let s be the function … See more The hairy ball theorem of algebraic topology (sometimes called the hedgehog theorem in Europe) states that there is no nonvanishing continuous tangent vector field on even-dimensional n-spheres. For the ordinary sphere, or … See more Every zero of a vector field has a (non-zero) "index", and it can be shown that the sum of all of the indices at all of the zeros must be two, because the Euler characteristic of the 2-sphere is two. Therefore, there must be at least one zero. This is a … See more The connection with the Euler characteristic χ suggests the correct generalisation: the 2n-sphere has no non-vanishing vector field for n ≥ 1. The difference between even and odd dimensions is that, because the only nonzero See more • Fixed-point theorem • Intermediate value theorem • Vector fields on spheres See more A common problem in computer graphics is to generate a non-zero vector in R that is orthogonal to a given non-zero vector. There is no single continuous function that can do this for all … See more There is a closely related argument from algebraic topology, using the Lefschetz fixed-point theorem. Since the Betti numbers of … See more The hairy ball theorem has numerous physical exemplifications.
