Let
M
:=
C
P
n
{\displaystyle M:=\mathbb {C} P^{n}}
and define the
tautological line bundle
over
C
P
n
{\displaystyle \mathbb {C} P^{n}}
to be the vector bundle
τ
:=
{
(
[
z
]
,
x
)
∈
C
P
n
×
C
|
x
∈
[
z
]
}
{\displaystyle \tau :=\{([z],x)\in \mathbb {C} P^{n}\times \mathbb {C} |x\in [z]\}}
with the projection
π
:
(
[
z
]
,
x
)
↦
[
z
]
{\displaystyle \pi :([z],x)\mapsto [z]}
. Find natural local trivialisations of
τ
{\displaystyle \tau }
that turn
τ
{\displaystyle \tau }
into a holomorphic line bundle.
