The dimension and generators of the three-particle kinematic variety in dimension three
The three-particle dimension-three conjecture. The variety $\mathcal{K}^{(3)}_{3,n}$ has dimension $3n-8$ . Its points are tensors $ST$ of multilinear rank at most $(2,4,2)$ . Here…

The residue-class description of order-two kinematic varieties
The residue-class description. For $d \equiv 0,1,6,7 \pmod{8}$ , the kinematic variety $\mathcal{K}^{(2)}_{d,n}$ consists of all symmetric $n\times n$ matrices with zero diagonal an…
