Ambient space (mathematics) explained

(l)

may be studied in isolation —in which case the ambient space of

l

is

l

, or it may be studied as an object embedded in 2-dimensional Euclidean space

(R2)

—in which case the ambient space of

l

is

R2

, or as an object embedded in 2-dimensional hyperbolic space

(H2)

—in which case the ambient space of

l

is

H2

. To see why this makes a difference, consider the statement "Parallel lines never intersect." This is true if the ambient space is

R2

, but false if the ambient space is

H2

, because the geometric properties of

R2

are different from the geometric properties of

H2

. All spaces are subsets of their ambient space.
