Graduate Connection between modified Bessel and hypergeometric fct's
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- ruwn

Graduate Connection between Lie-Brackets an Embeddings
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...- ruwn

Graduate Yau's result for the Ricci curvature on Kahler manifold
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...- ruwn
