weakly holomorphic


Let V be a local complex analytic variety.A function f:UV (where U is open in V)is said to be weakly holomorphic through Uif there exists a nowhere dense complex analytic subvariety WVand W contains the singular pointsMathworldPlanetmathPlanetmath of V and VWU,and such that f is holomorphic on VW andf is locally bounded on V.

It is not hard to show that we can then just take W to be the set of singularpoints of V and have U=VW as we can extend f to all thenonsingular points of V.

Usually we denote by 𝒪w(V) the ring of weakly holomorphic functionsthrough V. Since any neighbourhood of a point p in V is a local analytic subvariety,we can define germs of weakly holomorphic functions at p in the obvious way. We usuallydenote by 𝒪pw(V) the ring of germs at p of weakly holomorphicfunctions.
