Connection of Words
1.
C is complex plane.
is unit disk which center is the origin of
C.
z,
w are the two points of
.Hyperbolic distance
between
z and
w are defined by the next.
,
.
2.
M is complex manifold.
x,
y are arbitrary points of
M.
fv is finite sequence of regular curve.
Point
zv is
.
,
.
.{
} is called regular chain.Kobayashi pseudodistance
dM is defined by the next.
.
3.
[Interpretation on 2.]
:= Meaning minimum of word.
dM := Distance of word.M:= Word.
4.
[Definition]
When dM becomes distance function, M is called Kobayashi hyperbolic.
When dM becomes complete distance, M is called complete Kobayashi hyperbolic.
5.
When
M =
is satisfied at
dM ,
dM is equal to Poincaré distance.
6.
X is complex manifold.
M is contained in
X as relative compact.
7.
[Definition]
What embedding

[Theorem,Kwack 1969]
When
M is hyperbolicly embedding in
X,
What arbitrary regular map
\{0}
