The nonexistence of rank 4 IP tensors in signature (1,3) by Kelly Jeanne Pearson, Tan Zhang

“…Let V be a real vector space of dimension 4 with a nondegenerate symmetric bilinear form of signature (1,3). We show that there exists no algebraic curvature tensor R on V so that its associated skew-symmetric operator R(⋅) has rank 4 and constant eigenvalues on the Grassmannian of nondegenerate 2-planes in V.…”

Performance Analysis for Wireless Networks: An Analytical Approach by Multifarious Sym Teredo by D. Shalini Punithavathani, Sheryl Radley

“…However, the proposed tunneling protocol works with the symmetric and asymmetric NATs. In order to make a Teredo support several symmetric NATs along with several asymmetric NATs, we propose multifarious Sym Teredo (MTS), which is an extension of Teredo with a capability of navigating through several symmetric NATs. …”
