CMSA Room G10 CMSA, 20 Garden Street, Cambridge, MA, United StatesAlgebra Seminar Speaker: Lazar Guterman, Hebrew University of Jerusalem Title: Electrical networks, Grassmannians, and cluster algebras Abstract: An electrical network with $n$ boundary vertices induces a matrix called the response matrix which measures the electrical properties of the network. The set of response matrices of all electrical networks has a characterization in terms of positivity of […]
