Theorem 1.3 (Moore-Aronszajn [1]) Given a symmetric, positive de nite kernel kon a set X, there is a unique Hilbert space of functions on Xfor which kis a reproducing kernel. Proof: Most of the proof is by construction.
WebMercer's theorem states that the spectral decomposition of the integral operator of yields a series representation of in terms of the eigenvalues and eigenfunctions of . This then implies that is a reproducing kernel so that the corresponding RKHS can be defined in terms of these eigenvalues and eigenfunctions. We provide the details below. WebAn interesting consequence of the Mercer theorem is that { 𝜙 } =1 ∞. forms an orthonormalbasis of ℋ -2. This was . proved in [2,4]. 2.Noncompact sequence of Sets with Mercer theorem .
