摘要：

In this paper, we investigate a system of quantum electrodynamics with cutoffs. The total Hamiltonian is a self-adjoint operator on a boson-fermion Fock space. It is shown that under spatially localized conditions and momentum regularity conditions, the total Hamiltonian has a ground state for all values of coupling constants. In particular, its multiplicity is finite.
