摘要：

A general method for the study of the complex zeros of the partition function for lattice theories with fermions is applied to compact U(1) with dynamical fermions. In particular, we obtain the zeros of the partition function on the complex quark mass plane. On a small 4(4) lattice we study in a systematic way the dependence of the zeros on the theory's parameters, on lattice artefacts and on the various tuning parameters we have implemented.
