给定J的一子模和自由分辨率,我们可以定义一个矢量值的剩余电流,它的湮灭子是J。我们对电流对asj进行分解,它对应于J的一次分解。作为一个工具,我们引入了一类电流,包括通常的剩余电流和主值电流;特别地,这些潮流承认对解析变分和更一般地对可构造集有某种类型的限制。
Abstract Given a submodule and a free resolution of J one can define a certain vector-valued residue current whose annihilator is J. We make a decomposition of the current with respect to Ass J that corresponds to a primary decomposition of J. As a tool we introduce a class of currents that includes usual residue and principal value currents; in particular these currents admit a certain type of restriction to analytic varieties and more generally to constructible sets.
