TYP::Ish -- tests whether the argument is a product of generators of the h-basis

Call(s)


TYP::Ish(expr)

Parameters

expr- any expression

Introduction

The TYP::Ish function tests whether expr is a product of generators of the h-basis that is a product of complete symmetric functions.

The indexing vector must be a partition.

Example 1

>> muEC::TYP::Ish( h[] );
                                   TRUE
>> muEC::TYP::Ish( h[3,2,2,1] );
                                   TRUE
>> muEC::TYP::Ish( h[2,3,2,1] );
                                   FALSE
