Finiteness of Words

TANAKA Akio

[Preparation 1]
k is algebraic field.
is finite subset.
V is projective algebraic manifold over k.
D is defined divisor over k.
All the sub-manifolds are over k.
Rational point is k-rational point.

[Preparation 2]
L is rich line bundle.
|L| is complete linear system.
D is divisor of |L|.
is regular cut to D.
is approximate function to D.
is counting function to D.
is rich line bundle.
When islarge, becomes rich.
is basis of .
is embedding.

[Definition 1]
,
,
.

[Definition 2]
Subset of rational points \ is integer under the next condition.
(i) There exists a certain constant .
(ii) \ .

[Theorem, Faltings]
A is Abelian variety over k.
When D is reduced rich divisor, arbitrary integer subset \ is always finite set.

[Interpretation]
D is meaning minimum.
\ is word.
A is language.
