WebMay 23, 2014 · 1. Introduction. Since cluster algebras were introduced by Fomin and Zelevinsky [], it has been recognized that cluster algebra structures on homogeneous coordinate rings on Grassmannians are among the most important classes of examples.The demonstration of the existence of such a structure is due to Scott [] and one reason for … 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”. For a quantum Grassmannian …
