Dm. Carlucci et C. Dedominicis, ON THE REPLICA FOURIER-TRANSFORM, Comptes rendus de l'Academie des sciences. Serie II. Mecanique, physique, chimie, astronomie, 325(9), 1997, pp. 527-530
The Replica Fourier Transform introduced previously is related to the
standard definition of Fourier transforms over a group. Its use is ill
ustrated by block-diagonalizing the eigenvalue equation of a four-repl
ica Parisi matrix.
