Algorithm to find a maximum of a multilinear map over a product of spheres
We provide an algorithm to compute the 2-norm maximum of a multilinear map
over a product of spheres. As a corollary we give a method to compute the first
singular value of a linear map and an application to the theory of entangled
states in quantum physics. Also, we give an application to find the closest
rank-one tensor of a given one
