Block diagonalization algorithm join github today github is home to over 28 million developers working together to host and review code, manage projects, and build software together. We present new results on the block-diagonalization of operators with spectral gaps, based on a method of langer and tretter, and apply them to dirac operators on three-dimensional euclidean space with unbounded potentials. We consider the hamiltonian coupled-mode system that occur in nonlinear optics, photonics, and atomic physics spectral stability of gap solitons is determined.
