  • On the generating graph of a simple group 

    Lucchini, Andrea; Maroti, Attila; Roney-Dougal, Colva Mary (2016-09-26) - Journal article
    The generating graph Γ(H) of a finite group H is the graph defined on the elements of H, with an edge between two vertices if and only if they generate H. We show that if H is a sufficiently large simple group with Γ(G) ≅ ...
  • Persistent identification and citation of software 

    Jones, Catherine Mary; Matthews, Brian; Gent, Ian; Griffin, Tom; Tedds, Jonathan (2016) - Journal article
    Software underpins the academic research process across disciplines. To be able to understand, use/reuse and preserve data, the software code that generated, analysed or presented the data will need to be retained and ...
  • The classification of partition homogeneous groups with applications to semigroup theory 

    André, Jorge; Araúo, Joāo; Cameron, Peter Jephson (2016-04-15) - Journal article
    Let λ=(λ1,λ2,...) be a partition of n, a sequence of positive integers in non-increasing order with sum n. Let Ω:={1,...,n}. An ordered partition P=(A1,A2,...) of Ω has type λ if |Ai|=λi.Following Martin and Sagan, we say ...
  • A dynamical definition of f.g. virtually free groups 

    Bennett, Daniel; Bleak, Collin (2016-02) - Journal article
    We show that the class of finitely generated virtually free groups is precisely the class of demonstrable subgroups for R. Thompson's group V . The class of demonstrable groups for V consists of all groups which can embed ...
  • PAEAN : portable and scalable runtime support for parallel Haskell dialects 

    Berthold, Jost; Loidl, Hans-Wolfgang; Hammond, Kevin (2016) - Journal article
    Over time, several competing approaches to parallel Haskell programming have emerged. Different approaches support parallelism at various different scales, ranging from small multicores to massively parallel high-performance ...
