Hartogs extension theorem


Theorem.

Suppose V is an analytic variety in an open set UCn (n2) of dimensionMathworldPlanetmath at most n-2 and suppose that f:U\VC is holomorphic. Then there exists a unique holomorphic extention of f to all of U.

Note that when V is 0 dimensional (a point) then this is just a special case of the Hartogs’ phenomenon. Also note the similarity to Riemann’s removable singularityMathworldPlanetmath theorem in several variables, where however we also assume that f is locally bounded.
