Summary

Information about an operator is lazily computed.

Extended Summary

The information includes the exact 1-norm of the operator, in addition to estimates of 1-norms of powers of the operator. This uses the notation of Computing the Action (2011). This class is specialized enough to probably not be of general interest outside of this module.
