  • What are examples of orthogonal spaces of multivariable functions?

I asked a question and learned that $$langle f(x_1,x_2,cdots x_n),g(x_1,x_2,cdots x_n) rangle = idotsint_D f(x_1,x_2,cdots x_n) overlineg(x_1,x_2,cdots x_n) dx_1dx_2cdots dx_n$$.

  • For real-valued functions on a given domain a dot product can be defined as the integral over that domain of the product of those functions and a fixed non-negative weight function. The spherical harmonics are an example.

  • @random Does that requires multiple integrals?
