SUMMARY
The discussion centers on the orthogonality of eigenfunctions associated with a linear operator \(\mathcal{L}\). It is established that eigenfunctions \(\phi_n\) of a self-adjoint operator are orthogonal due to the properties of inner products in Hilbert spaces. The referenced material provides a concise explanation of this principle, emphasizing the mathematical foundations that guarantee orthogonality in quantum mechanics and functional analysis.
