In mathematics, the BochnerâÂÂMartinelli formula is a generalization of the Cauchy integral formula to functions of several complex variables, introduced by and .
For , in the BochnerâÂÂMartinelli 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 <sup>n</sup> with piecewise smooth boundary . Then the BochnerâÂÂMartinelli formula states that if is in the domain then
In particular if is holomorphic the second term vanishes, so
