Abstract: We show that the spectrum of the complex Laplacian $ \Box$ on a product of Hermitian manifolds is the Minkowski sum of the spectra of the complex Laplacians on the factors. We use this to show that the range of the Cauchy-Riemann operator $ \overline{\partial}$ is closed on a product manifold, provided it is closed on each factor manifold.
