A bundle map is a map between bundles along with a compatible map between the base manifolds. Suppose p:X->M and q:Y->N are two bundles, then F:X->Y is a bundle map if there ...

The definition of an Anosov map is the same as for an Anosov diffeomorphism except that instead of being a diffeomorphism, it is a map. In particular, an Anosov map is a C^1 ...

Informally, a symplectic map is a map which preserves the sum of areas projected onto the set of (p_i,q_i) planes. It is the generalization of an area-preserving map. ...

A continuous map f:X->Y between topological spaces is said to be null-homotopic if it is homotopic to a constant map. If a space X has the property that id_X, the identity ...

If a map f:G->G^' from a group G to a group G^' satisfies f(ab)=f(b)f(a) for all a,b in G, then f is said to be an antihomomorphism.

Every continuous map f:S^n->R^n must identify a pair of antipodal points.

The study of map projections and the making of geographical maps.

A diffeomorphism is a map between manifolds which is differentiable and has a differentiable inverse.

A map which is monotone increasing and therefore order-preserving.

A nonsingular linear map A:R^n->R^n is orientation-preserving if det(A)>0.
