D.5.20 JMSConst_lib

Library:

JMSConst.lib

Purpose:

A library for Singular which constructs J-Marked Schemes.

Author:

Michela Ceria, email: michela.ceria@unito.it

Overview:

The library performs the J-marked computation, as described in [BCLR]. As in JMBTest.lib we construct the V polynomials and we reduce the EK polynomials w.r.t. them, putting the coefficients as results.

The algorithm terminates only if the ordering is ip. Anyway, the number of reduction steps is bounded.
