3 Uniqueness of Word
TANAKA Akio
Conjecture
Word has uniqueness.
[Explanation]
1
Smooth manifold M
Hermitian metric of M h
Tangent bundle of TM
positive definite Hermitian inner product over TM h

Smooth manifold M
Hermitian metric of M h
Tangent bundle of TM
positive definite Hermitian inner product over TM h
Local
coordinate system z1,
..., zn
Hermitian
symmetric positive definite function's matrix hij
h
= hijzij
Correspondence differential form w
Correspondence differential form w
w = hijdzidj
When dw = 0, h is called Kller metric and w is called Kllerform.
Complex
manifold that has Kller metric Kller manifold
2
n-dimensional compact Kller manifold X
Kller metric of X g
Correspondence
Kller form w
Local
coordinate system z1,
..., zn
Ricci
curvature of X
R = - log det (g)
Ricci
form Ric(w) = Rdzd
A
certain constant
c
When
Ric(w) = cw, g is called Kller-Einstein metric.
When c = 0, c1(X) = 0
When c = -1, Linear bundle nTX
's cobundle is ample. The situation is briefly abbreviate expressed by c1(X) <0.
3
Compact
Kller manifold X
X
satisfies c1(X) = 0 or c1(X) <0.
When Kller form's cohomology class is fixed, Kller-Einstein metric exists uniquely.
When Kller form's cohomology class is fixed, Kller-Einstein metric exists uniquely.
[Comment]
When
word is expressed by compact Kller manifold in adequate condition, word has
uniqueness.
