Complex Manifold Deformation Theory 

1 Distance of Word

TANAKA Akio  



Conjecture
Word has distance.

[Explanation]
1
Topological space     E, B, F
Continuous map     : EF
Homeomorphic withF     -1 (b) , bB    
Neighborhood of b     U B  
Homeomorphic with U F     -1 (U)
Homeomorphic map     h : -1 (U) U F
Objection to primary component     p1U F   U  
, h and p1 are fiber bundle in total space S, base space B, fiber F and projection .

2
Topological space     E
Family that consists of E's open sets     {U }aA
What E is covered by {Ua}aA is that the next is satisfied.
E = aAUa
Open sets family { Ua}aA is called open covering.
What covering is simply connected in space is called unversal covering.

3
Complex manifold     M
Point of M     Q
Normal tangent vector space     TQ(M)
m+n dimensional complex manifold     V
m dimensional complex manifold      W
Holomorphic map     : VW
Map that satisfies the next is called analytic family of compact complex manifolds.
(i) is proper map.
(ii) is smooth holomorphic map.
(iii) For arbitrary point of wW, fiber -1 (w) is always connected.
When w0W is fixed, VwwW is called deformation of Vw0.

4
Complex manifold     S
Weight     w
Deformation of polar
Z-Hodge structure     H = (HZ, F, )
Point     s0 S
H
Z = HZ (s0)
Fp = Fp(s0)
=  (s0)
Polar Z-Hodge structure     (H
Z, {Fp}, )
Period dmain that is canonical by (H
Z, { Fp}, )     D
compact relative of D    
Bilinear form over HZ, that is determend by    Q
Monodromy expression of S's fundamental group (S, s0)       : 1 (S, s0) G
Z = Aut(HZ, Q)
 = Im =   ( 1 (S, s0) )
 : S \ D
  is called period map.

5
Compact manifold     M
Horizontal tangent bundle     Th
Regular map      : M  
Horizontal     d is map that is from TM to Th()
Locally liftable     | V : V D \ D

6
Subring of
R      A
H = (HA, F) that satisfies the next is called weight w's A-Hodge structure.
(i) HA is finite generative A module.
(ii) For arbitrary p, q, there exists decomposition H
C= p+q=wHp,q that satisfies Hp,q = Hp,q .   Hp,q is complex conjugate for Hp,q .

7
A-Hodge's deformation over S      H = (HA, F),  H' = (H'A, F)   
Morphism of A module's local constant sheaf      fA: HA H'A
f
o= fAAO : HOH'O that is compatible with filter F is called sheaf from H to H'.

8
Deformation's morphism of Hodge structure     : H HAA (-w)
sS
Fiber A(s)= A,s
Weight     w
 that gives polar of w's A-Hodge structure at s is called polar of deformation of w's A-Hodge structure's deformation.
Hodge structure that is associated with polar is called polarized VHS.

9
Open diskD = { z
C | |z|<1 }, D* = D\{0}
Universal covering of D*     Upper half-plane of Poincaré     
 H
Covering map    
z exp(2z) D*
Polarized VHS on D     (
H,S)

Fundamental group     1(D*)   Z
Generation element of the fundamental group     H
C
Action as monodromy to H
C     T
Period map adjoint with H     p : H D
p ( z + 1 ) = Tp(z)

10
O module of deformation of Hodge structure H     HO
D* = D\{0}
Period map     p : D* \ D
Limit of p   limz0p(z)
Unversal covering    
HD

11
Period map    
Nilpotent orbit    (w) : = exp(wN) (0)
(Nilpotent orbit theorem)
(i) Nipotent orbit is horizontable map.
(ii) If Im w > 0 is enough large, (w) D.
(iii) If Im w > 0 is enough large, there exists non-negative constant B that satisfies dD((w), (w) )(Imw)Be-2Imw .
     dD is invariant distance over D.

[Comment]
When word is expressed by open disk D, word has invariant distance in adequite condition(Im w > 0).
At that time, B is proper number of its word.
