Type | Article in Journal |

Abstract | We give an approximate division algorithm in the ring of analytic differential operator D ̂ . By using this approximate division algorithm and the Mora division algorithm for differential operator, we can compute the local b function. |

Keywords | Division in the ring of analytic differential operators, Mora division algorithm, b -function, Local b -function |
