TYP::Ise -- tests whether the argument is a product of generators of the e-basis

Call(s)


TYP::Ise(expr)

Parameters

expr- any expression

Introduction

The TYP::Ise function tests whether expr is a product of generators of the e-basis that is a product of elementary symmetric functions.

The indexing vector must be a partition.

Example 1

>> muEC::TYP::Ise( e[] );
                                   TRUE
>> muEC::TYP::Ise( e[3,2,2,1] );
                                   TRUE
>> muEC::TYP::Ise( e[2,3,2,1] );
                                   FALSE
