Let … WebView history Hans Grauert (8 February 1930 in Haren, Emsland, Germany – 4 September 2011) was a German mathematician. He is known for major works on several complex variables, complex manifolds [1] and the application of sheaf theory in this area, which influenced later work in algebraic geometry. [2]
WebIn 1939 K. Oka [49] proved the following theorem. Let D ℂ C n be a domain of holomorphy, let {U i} i∈I be an open covering of D, and let c i: U i ↦ C 1 \O, i∈I, be a family of continuous functions such that the functions c j /c i are holomorphic on U i H U j. Then there exists a family of holomorphic function h i: U i C 1 \O such that h j /h i = c j /c i on U i H U j. ... WebVanishing theorem.
