Aspects of order and congruence relations on regular semigroups
(University of St Andrews, 1983) - ThesisOn a regular semigroup S natural order relations have been defined by Nambooripad and by Lallement. Different characterisations and relationships between the Nambooripad order J, Lallement's order λ and a certain relation ... -
Graph automatic semigroups
(University of St Andrews, 2016-06-24) - ThesisIn this thesis we examine properties and constructions of graph automatic semigroups, a generalisation of both automatic semigroups and finitely generated FA-presentable semigroups. We consider the properties of graph ... -
Effects of thermal conduction and compressive viscosity on the period ratio of the slow mode
(2010-06) - Journal articleAims: Increasing observational evidence of wave modes brings us to a closer understanding of the solar corona. Coronal seismology allows us to combine wave observations and theory to determine otherwise unknown parameters. ... -
Dimension and measure theory of self-similar structures with no separation condition
(University of St Andrews, 2015-11-30) - ThesisWe introduce methods to cope with self-similar sets when we do not assume any separation condition. For a self-similar set K ⊆ ℝᵈ we establish a similarity dimension-like formula for Hausdorff dimension regardless of any ... -
On generators, relations and D-simplicity of direct products, Byleen extensions, and other semigroup constructions
(University of St Andrews, 2015-11-30) - ThesisIn this thesis we study two different topics, both in the context of semigroup constructions. The first is the investigation of an embedding problem, specifically the problem of whether it is possible to embed any given ...
