[L^p Spaces and Convergence of Fourier Series
Throughout these notes, we let K = R or K = C. We use the symbol :, for example, Let f = LP ([0,2]) for 1 <p<∞. Define the Fourier series of f and analyze the
f(x)= r² to say that the function f is defined by setting f(x) = r for all in the domain.
This is same as writing f(x) def 2. Can you guess what the symbol 2: f(x) means?
