  • Proof search issues in some non-classical logics 

    Howe, Jacob M. (University of St Andrews, 1999) - Thesis
    This thesis develops techniques and ideas on proof search. Proof search is used with one of two meanings. Proof search can be thought of either as the search for a yes/no answer to a query (theorem proving), or as the ...
  • Chains of subsemigroups 

    Cameron, Peter J.; Gadouleau, Maximilien; Mitchell, James D.; Peresse, Yann (2017-06) - Journal article
    We investigate the maximum length of a chain of subsemigroups in various classes of semigroups, such as the full transformation semigroups, the general linear semigroups, and the semigroups of order-preserving transformations ...
  • Imprimitive permutations in primitive groups 

    Araújo, Joao; Araújo, Joao Pedro; Cameron, Peter Jephson; Dobson, Ted; Hulpke, Alexander; Lopes, Pedro (2017-09-15) - Journal article
    The goal of this paper is to study primitive groups that are contained in the union of maximal (in the symmetric group) imprimitive groups. The study of types of permutations that appear inside primitive groups goes back ...
  • On the Hausdorff and packing measures of typical compact metric spaces 

    Jurina, S.; MacGregor, N.; Mitchell, A.; Olsen, L.; Stylianou, A. (2018-04-24) - Journal article
    We study the Hausdorff and packing measures of typical compact metric spaces belonging to the Gromov–Hausdorff space (of all compact metric spaces) equipped with the Gromov–Hausdorff metric.
  • On well quasi-order of graph classes under homomorphic image orderings 

    Huczynska, S.; Ruškuc, N. (2017-06) - Journal article
    In this paper we consider the question of well quasi-order for classes defined by a single obstruction within the classes of all graphs, digraphs and tournaments, under the homomorphic image ordering (in both its standard ...
