　　摘要：We consider the quotient module Q of the Hardy module defifined by an analytic set satisfying certain conditions. Solving a previouslyraised problem, we show that certain 2d-antisymmetric sums of module operators are in the trace class. In the case d=1, we derive a trace formula on Q, which answers another previously-raised question.
