| Résume | Spectral synthesis is the possibility of a reconstruction of the whole lattice
of invariant subspaces of a linear operator from generalized eigenvectors.
A closely related problem is the reconstruction of a vector in a Hilbert space from its Fourier series with respect to some complete and minimal system. We discuss the spectral synthesis problem in the context of operator and function theory and present several recent advances in this area. Among them is the solution of the spectral synthesis problem for systems of exponentials on an interval as well as some results about the synthesis for phase-space shifts of the Gaussian on the line.
