## Statement

###### Theorem

Cartan’s theorem B

On a Stein manifold $\Sigma$ and for $A$ an analytic coherent sheaf on $\Sigma$ then all the positive-degree abelian sheaf cohomology groups of $\Sigma$ with coefficients in $A$ vanish:

$H^{\bullet \geq 1}(\Sigma, A) = 0 \,.$

This is recalled for instance as (Forstnerič 11, theorem 2.4.1)

###### Theorem

Also all positive-degree Dolbeault cohomology groups vanish:

$H^{\bullet, \bullet \geq 1}_{\bar \partial}(\Sigma) = 0 \,.$

This is recalled for instance in (Forstnerič 11, theorem 2.4.6, Gunning-Rossi).
