In mathematics, the Bochner–Martinelli formula is a generalization of the
Cauchy integral formula to functions of
several complex variables
The theory of functions of several complex variables is the branch of mathematics dealing with complex-valued functions. The name of the field dealing with the properties of function of several complex variables is called several complex variable ...

History
Bochner–Martinelli kernel
For , in
the Bochner–Martinelli kernel is a differential form in of bidegree defined by
:
(where the term is omitted).
Suppose that is a continuously differentiable function on the closure of a domain in
''n'' with piecewise smooth boundary . Then the Bochner–Martinelli formula states that if is in the domain then
:
In particular if is holomorphic the second term vanishes, so
