WebHilbert space was found to be very useful for the formu-lations in quantum mechanics (Prugovecki,1982). After the initial works on Hilbert space by Hilbert and Schmidt (Hilbert,1904;Schmidt,1908), James Mercer improved Hilbert’s work and proposed his theorem in 1909 (Mer-cer,1909) which was named the Mercer’s theorem later. http://staff.ustc.edu.cn/~wangzuoq/Courses/20F-SMA/Notes/Lec13.pdf
