# This is a python script to verify all manifolds in the cusped census. To show that a manifold is # hyperbolic we only need to show that one triangulation of a given manifold is provably hyperbolic # by our method. In fact, we show that either the given triangulation of snappy is provably hyperbolic # or the canonical triangulation is. Although with enough precision, one should be able to verify # that all triangulations in the census are hyperbolic, checking either one is sufficient for our # purposes. import hikmot import snappy Census = snappy.OrientableCuspedCensus() print_data = 0 save_data = 0 GoodList=[] BadList=[] for M in snappy.OrientableCuspedCensus(): N = M.copy() N.canonize() if (hikmot.verify_hyperbolicity(N,print_data, save_data)[0] or hikmot.verify_hyperbolicity(M,print_data, save_data)): # and M.is_isometric_to(N): GoodList.append(N) else: BadList.append(N) print " N=",N, " M=",M, " iso ", M.is_isometric_to(N), " hikmot ", hikmot.verify_hyperbolicity(M,print_data, save_data)[0] print 'Out of', len(Census), ' manifolds in the OrientableCuspedCensus,', len(GoodList), ' have been proven to be hyperbolic and ', len(BadList), ' have not.'
