  The new light-front coupled-cluster (LFCC) method for the nonperturbative
solution of Hamiltonian eigenvalue problems is described and then illustrated
in an application to quantum electrodynamics. The method eliminates any
necessity for a Fock-space truncation and thereby avoids complications
associated with such a truncation. An LFCC calculation of the electron's
anomalous magnetic moment is formulated for a truncation that, for simplicity,
excludes positrons but keeps arbitrarily many photons.
