Detailed Description

Class inherited from std::vector<int>, dynkin labels for a state of a semi-simple algebra (see documentation od SemiSimpleAlgebra).

Constructor & Destructor Documentation

AlgebraState()

mty::AlgebraState::AlgebraState ( const std::vector< int > &  vec )

inlineexplicit

Constructor with one parameter.

Parameters

vec	std::vector of int containing the dinkin labels of the state.

Member Function Documentation

applyAnnihilator()

AlgebraState mty::AlgebraState::applyAnnihilator

(

const std::vector< int > &

shifts

)

const

Applies shifts on labels coming from annihilation operators. Creates a new state with labels "labels - shift".

Parameters

shifts

std::vector of int with a size corresponding to the number of labels.

Returns

The modified state with shifts applied.

eigenValue()

int mty::AlgebraState::eigenValue	(	const std::vector< int > &	root,
		const std::vector< int > &	normRoots,
		int	normLambda
	)		const

Calculates the eigenvalue of the state with respect to the root root, considering l simple roots (then l dinkin labels).

Parameters

root	Dinkin labels of the root (size l).
normRoots	Norm of the l simple roots.
normLambda	Norm of the root \( \lambda \).

Returns

The eigenvalue of the state with respect to root.

getLabels()

vector< int > mty::AlgebraState::getLabels

(

)

const

Converts the state into a simple std::vector of int corresponding to the l dinkin labels of the state.

Returns

The dinkin labels of the state in a std::vector<int>.

Friends And Related Function Documentation

operator<<

std::ostream& operator<< ( std::ostream &  fout, const AlgebraState &  state  )

friend

Overload of the operator<< for AlgebraState, displays the labels in the output fout.

Parameters

fout	Output flux.
state	AlgebraState to display.

Returns

The modified flux.
