    • Semigroup congruences : computational techniques and theoretical applications 

      Torpey, Michael (University of St Andrews, 2019-06-25) - Thesis
      Computational semigroup theory is an area of research that is subject to growing interest. The development of semigroup algorithms allows for new theoretical results to be discovered, which in turn informs the creation ...

    • 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, ...

    • Randomness as a computational strategy : on matrix and tensor decompositions 

      Erichson, N. Benjamin (University of St Andrews, 2017-11-20) - Thesis
      Matrix and tensor decompositions are fundamental tools for finding structure and data processing. In particular, the efficient computation of low-rank matrix approximations is an ubiquitous problem in the area of machine ...

    • 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 ...
