My question is: what is meant by "appearing only once" in the Hilbert space?

"WebAbstract: The Weil representation gives an algebraic method to classify the irreducible representations of symplectic groups Sp(2n,Fq). In this talk, we will work out this method on Sp(2,Fq) = SL(2,Fq), and show how in this case, it associates to each irreducible representation of SL(2,Fq) a maximal torus.
