A Cambrian framework for the oriented cycle
Nathan Reading, David E. Speyer
This paper completes the project of constructing combinatorial models (called frameworks) for the exchange graph and g-vector fan associated to any exchange matrix B whose Cartan c…
Combinatorial frameworks for cluster algebras
Nathan Reading, David E Speyer
We develop a general approach to finding combinatorial models for cluster algebras. The approach is to construct a labeled graph called a framework. When a framework is constructed…
Sortable Elements for Quivers with Cycles
Nathan Reading, David E Speyer
Each Coxeter element c of a Coxeter group W defines a subset of W called the c-sortable elements. The choice of a Coxeter element of W is equivalent to the choice of an acyclic ori…
The fundamental theorem of finite semidistributive lattices
Nathan Reading, David E Speyer, Hugh Thomas
We prove a Fundamental Theorem of Finite Semidistributive Lattices (FTFSDL), modelled on Birkhoff's Fundamental Theorem of Finite Distributive Lattices. Our FTFSDL is of the form "…
