    • Constructing isostatic frameworks for the l1 and l infinity plane (Pre-published) 

      Clinch, Katie; Kitson, Derek (Electronic Journal of Combinatorics, 2020-06-12)
      We use a new coloured multi-graph constructive method to prove that if the edge-set of a graph G = (V,E) has a partition into two spanning trees T1 and T2 then there is a map p : V → R2, p(v) = (p(v)1,p(v)2), such that ...

    • Symbol functions for symmetric frameworks (Pre-published) 

      Kitson, Derek; Kastis, Eleftherios; McCarthy, John E (Elsevier, 2021-05-15)
      We prove a variant of the well-known result that intertwiners for the bilateral shift on ℓ2(Z) are unitarily equivalent to multiplication operators on L2(T). This enables us to unify and extend fundamental aspects of ...
