The geometric measure of multipartite entanglement and the singular values of a hypermatrix
Joseph J. Hilling, Anthony Sudbery · Journal of Mathematical Physics · 2010
It is shown that the geometric measure of entanglement of a pure multipartite state satisfies a polynomial equation, generalizing the singular-value equation of the matrix of coefficients of a bipartite state. The equation is solved for a class of three-qubit states.
