weakly holomorphic
Let be a local complex analytic variety.A function (where is open in )is said to be weakly holomorphic through if there exists a nowhere dense complex analytic subvariety and contains the singular points of and ,and such that is holomorphic on and is locally bounded on .
It is not hard to show that we can then just take to be the set of singularpoints of and have as we can extend to all thenonsingular points of .
Usually we denote by the ring of weakly holomorphic functionsthrough . Since any neighbourhood of a point in is a local analytic subvariety,we can define germs of weakly holomorphic functions at in the obvious way. We usuallydenote by the ring of germs at of weakly holomorphicfunctions.
