摘要翻译:
以前,作者考虑并在某些情况下计算了复(法)曲面奇点上(特别是复平面上)函数芽环上两类多指标过滤的Poincare级数。第一类的过滤由曲面奇异性上的一条曲线(有几个分支)定义。另一种方法(所谓的除法滤波)是由曲面奇异性修正的例外除子的一组分量定义的。本文定义了曲面奇点上函数芽环中对应于理想或理想集的滤子,并在某些情况下计算了相应的Poincare级数。对于复平面,这个概念将上面描述的两类过滤结合在一起。

英文摘要:
Earlier the authors considered and, in some cases, computed Poincare series of two sorts of multi-index filtrations on the ring of germs of functions on a complex (normal) surface singularity (in particular on the complex plane). A filtration from the first class was defined by a curve (with several branches) on the surface singularity. The other one (so called divisorial filtration) was defined by a set of components of the exceptional divisor of a modification of the surface singularity. Here we define a filtration corresponding to an ideal or to a set of ideals in the ring of germs of functions on a surface singularity and compute the corresponding Poincare series in some cases. For the complex plane this notion unites the two classes of filtrations described above.
