WebWeb bases in the sl2 and sl3 cases are important in cluster algebra structure of Grassmannian coordinate rings [FP16, Fra20]. While cluster algebras from coordinate rings of partial ag varieties (e.g., [GLS08]) have been comparatively less studied, we believe that the pieces of these coordinate WebJul 1, 2024 · We provide a cluster-algebraic approach to the computation of the recently introduced generalised biadjoint scalar amplitudes related to Grassmannians ${\\rm Gr}(k,n)$. A finite cluster algebra provides a natural triangulation for the tropical Grassmannian whose volume computes the scattering amplitudes. Using this method …
