Uniqueness questions in a scaling-rotation geometry on the space of symmetric positive-definite matrices

David Groisser, Sungkyu Jung, Armin Schwartzman

Jung et al. (2015) introduced a geometric structure on ${\mathrm{Sym}}^{+}(p)$, the set of $p\times p$ symmetric positive-definite matrices, based on eigen-decomposition. Eigenstructure…
