check if a LHPDEs system is in rif-reduced form
check if a LHPDEs system is rif-reduced with respect to a total degree ranking
a LHPDE object
The IsRifReduced method returns true if a LHPDE object is in rif-reduced form, false otherwise. It returns FAIL if the status is unknown.
Let S be a LHPDE object. The IsTotalDegreeRanking method checks if S is rif-reduced with respect to a total degree ranking (see ranking for more detail). It returns FAIL if S is not in rif-reduced form.
For setting a LHPDEs system as being in a rif-reduced form, see LieAlgebrasOfVectorFields[LHPDE]. And, to rif-reduce a LHPDE object, see the RifReduce method.
These methods are associated with the LHPDE object. For more detail, see Overview of the LHPDE object.
The status of S1 for being a rif-reduced form is not known:
Therefore, information will not be available..
The IsRifReduced and IsTotalDegreeRanking commands were introduced in Maple 2020.
For more information on Maple 2020 changes, see Updates in Maple 2020.
