: holomorphic principle bundle representation
Fiber is
consider sections of
,
f is holomorphic iff
.
necessary condition for existence of f is
This means
in other
words, a portion of the curvature must be 0.
curvature = 0 for the antiholomorphic part means
with
, not necessarily
in G.
If you generalize gauge to
then you can choose:
and
.
Then the covariant derivatives:
, satisfy:
Then
simplifies too
.
Example of holomorphic vector bundle: tangent bundles
Theorem: holomorphic principle bundle, P(M,G), then for every representation
p of G,
an associated holomorphic vector bundle
.
To prove this, relate
to
via transition functions. Then derive
that
.
To holomorphic transition functions
and
are equivalent iff
where
are holomorphic.
