    "abstract": "Degeneracies in the spectrum of an adiabatically transported quantum system\nare important to determine the geometrical phase factor, and may be interpreted\nas magnetic monopoles. We investigate the mechanism by which constraints acting\non the system, related to local symmetries, can create arbitrarily large\nmonopole charges. These charges are associated with different geometries of the\ndegeneracy. An explicit method to compute the charge as well as several\nillustrative examples are given.",
