p**n
发帖数: 10 | 1 I desperately need help now.
anyone can lecture me on how to expand a function f(x), where x is a vector in
4-dimension space, as a sum of ultraspherical harmonic. I know how to do this
in 3-dimension, i.e. f(x) can be expanded as spherical harmonics Y_lm(\theta,
\phi). every text book has it. If we generalize it to higher dimension, such
as 4-d, it is my quesion. I dont want it to be very theoretical, but I want it
practical. And also, it should have othogonal properites as well...
