TYP::IsSkewPart -- tests whether the argument is a skew partition

Call(s)


TYP::IsSkewPart(expr)

Parameters

expr- any expression

Introduction

The TYP::IsSkewPart function tests whether expr is a skew partition that is a a list with two components l1 and l2, l1 being the exterior shape, l2 the interior shape. The diagram of bixes needs not to be connected, the condition being that the diagram of l2 must be included into the one of l1.

Example 1

>> muEC::TYP::IsSkewPart( [[3,1,1], [2,1]] );
                                   TRUE
>> muEC::TYP::IsSkewPart( [[4,2], [3,3]] );
                                   FALSE
