- In mathematics, a

bijective function, or one-to-one
correspondence is a
function between two sets such that each

- In mathematics, injections, surjections, and
bijections are
classes of
functions distinguished by the
manner in

- In
graph theory, an
isomorphism of
graphs G and H is a
bijection between the
vertex sets of G and H f : V ( G ) → V ( H ) {\displaystyle f\colon V(G)\to...

using a
method of

bijection will be
constructed between T and R. Therefore, T and R have the same...
- is that no
bijection can
exist between {1, 2, ..., n} and {1, 2, ..., m}
unless n = m; this fact (together with the fact that two
bijections can be composed...

- In
projective geometry, a
collineation is a one-to-one and onto map (a
