Abstract

In a recent paper, Drusvyatskiy, Lee, Ottaviani, and Thomas establish a “transfer principle” by means of which the Euclidean distance degree of an orthogonally-stable matrix variety can be computed from the Euclidean distance degree of its intersection with a linear subspace. We generalise this principle.
