Constructor & Destructor Documentation

◆ ~Irrep()

virtual mpqc::math::Group::Irrep::~Irrep ( )

inlinevirtual

Reimplemented in mpqc::math::groups::Irrep, and mpqc::math::groups::Z1::Irrep.

◆ Irrep()

mpqc::math::Group::Irrep::Irrep ( std::weak_ptr< const Group > grp )

protected

Member Function Documentation

◆ group()

const std::weak_ptr< const Group > & mpqc::math::Group::Irrep::group ( ) const

Returns: shared_ptr to the Group object that defines this

◆ is_trivial()

bool mpqc::math::groups::SupercellTranslationGroup::Irrep::is_trivial ( ) const

pure virtual

Returns: true if this is a trivial representation

Implemented in mpqc::math::groups::Irrep, and mpqc::math::groups::Z1::Irrep.

◆ tensor_product()

virtual std::vector<std::pair<unsigned int, std::shared_ptr<const Irrep> > > mpqc::math::Group::Irrep::tensor_product ( std::shared_ptr< const Irrep > other ) const

pure virtual

tensor product of 2 Irrep objects = a "linear combination" of Irrep objects
