A pair of Plücker coordinates can appear together in the same cluster if and only if they are labeled by weakly separated subsets of [n] delimited-[] 𝑛 [n] [ italic_n ].For Plücker coordinates that do not appear together in the same cluster, …

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 … WebIn this paper, we study quasi-homomorphisms of quantum cluster algebras, which are quantum analogy of quasi-homomorphisms of cluster algebras introduced by Fraser. Quasi-homomorphisms of quantum cluster algebras appeared in a work by Kimura, Qin, and Wei in 2024 which they called “variation maps”.

WebWhat do cluster algebras tell us about Grassmannians? One of the first examples of a cluster algebra given in Fomin and Zelevinsky's original paper is the homogeneous coordinate ring C [ G 2, n] of the Grassmannian of planes in C n. It has also been shown by Scott that C [ G k, n] carries a cluster algebra structure for any k. WebJul 28, 2024 · We construct Grassmannian categories of infinite rank, providing an infinite analogue of the Grassmannian cluster categories introduced by Jensen, King, and Su. Each Grassmannian category of infinite rank is given as the category of graded maximal Cohen-Macaulay modules over a certain hypersurface singularity. We show that …

WebIt is shown that many results on cluster algebras (the Laurent phenomenon, the classification of finite-type cluster algebras) extend to the quantum case. The important open problem is to show that quantum cluster monomials have non-negative coefficients. The paper under review deals with skew-symmetric acyclic quantum cluster algebras. The
