Closed string trajectories from a new “tiling”

Year: 2026

Type: article

Abstract: A bstract Based on an efficient technology for the excavation of entire open string trajectories of physical states, we propose an algorithmic method of constructing the largely unknown closed string trajectories. Due to combinatorial complexity, the “double copy” of open strings is limited in efficiency as a means of building closed string trajectories. We bypass this technical difficulty by employing one open string as the fundamental seed and then dressing it by a suitable selection of generators of a symplectic algebra that acts on both the left and the right sector. By applying Howe duality, the dressed seeds amount to closed string trajectory candidates, finding the physical subset of which is possible by solving systems of equations involving Diophantine-like recursion relations, which we also illustrate with examples.
