    • Maximal subsemigroups of finite transformation and diagram monoids 

      East, James; Kumar, Jitender; Mitchell, James D.; Wilson, Wilf A. (2018-06-15) - Journal article
      We describe and count the maximal subsemigroups of many well-known transformation monoids, and diagram monoids, using a new unified framework that allows the treatment of several classes of monoids simultaneously. The ...
    • Computing maximal subsemigroups of a finite semigroup 

      Donoven, C. R.; Mitchell, J. D.; Wilson, W. A. (2018-07-01) - Journal article
      A proper subsemigroup of a semigroup is maximal if it is not contained in any other proper subsemigroup. A maximal subsemigroup of a finite semigroup has one of a small number of forms, as described in a paper of Graham, ...
    • Phases of physics in J.D. Forbes’ Dissertation Sixth for the Encyclopaedia Britannica (1856) 

      Falconer, Isobel Jessie (2018-12-03) - Journal article
      This paper takes James David Forbes’ Encyclopaedia Britannica entry, Dissertation Sixth, as a lens to examine physics as a cognitive, practical, and social, enterprise. Forbes wrote this survey of eighteenth- and ...
    • Equilibrium states, pressure and escape for multimodal maps with holes 

      Demers, Mark F.; Todd, Mike (2017-09) - Journal article
      For a class of non-uniformly hyperbolic interval maps, we study rates of escape with respect to conformal measures associated with a family of geometric potentials. We establish the existence of physically relevant ...
    • Two variants of the froidure-pin algorithm for finite semigroups 

      Jonusas, Julius; Mitchell, J. D.; Pfeiffer, M. (2018-02-08) - Journal article
      In this paper, we present two algorithms based on the Froidure-Pin Algorithm for computing the structure of a finite semigroup from a generating set. As was the case with the original algorithm of Froidure and Pin, the ...
