hallo, i now spent an hour looking for a formula connecting the modified bessel functions I_n and K_n to the hypergeometrical series F(a,b;c;z). has somedoby an idea? thank you

Im sorry to bother you, but I am trying to understand one thing about embedding. Consider you have sphere embedded in the R^3, so you have a flat metrik. Otherwise you could describe the same sphere without embedding but with an induced metric. My problem is to make clear that the Lie-Brackets...

Kähler manifolds are hermitian manifolds with closed Kählerform. The Kählerform looks like the metrik tensor but is antisymmetric. if you impose that the exterior derivative of the kählerform vanishes you find that the metric can locally be expressed by the Kählerpotential. So if you got a...
