The Geometries of Jordan nets and Jordan webs

Arthur Bik, Henrik Eisenmann

A Jordan net (resp. web) is an embedding of a unital Jordan algebra of dimension $3$ (resp. $4$ ) into the space $S^{n}$ of symmetric $n \times n$ matrices. We study the geome…

Maximum relative distance between real rank-two and rank-one tensors

Henrik Eisenmann, André Uschmajew

It is shown that the relative distance in Frobenius norm of a real symmetric order- $d$ tensor of rank two to its best rank-one approximation is upper bounded by $\sqrt{1-(1-1/d)^{d…
