Description

We apply Luescher's definition of topological charge for lattice gauge field theories to the two-dimensional massless Schwinger model latticizing the vector field but keeping the fermions in the continuum. The instanton effects induced through fermion bilinears and the ensuing breakdown of cluster decomposition are discussed qualitatively in view of Luescher's concept. (orig.)
