Coulomb gas formalism in conformal field theoryMatthew Geleta
This thesis examines the Coulomb gas formalism in conformal field theory. It begins by developing the Coulomb gas formalism starting from a bosonic string theory. Some applications in statistical field theory are demonstrated by constructing minimal model conformal field theories and relating these to critical lattice models like the Ising model. The Coulomb gas formalism is then used to analytically compute primary three-point constants and operator product expansion coefficients for the minimal conformal field theories. Comparisons are made to results from other techniques like bosonization of the free fermion conformal field theory. The main original contribution is conjecturing and verifying a connection between the Coulomb gas formalism and the monodromy theory of certain Fuchsian

a) Walking on wet ice is difficult because ice is very slippery when wet, providing little friction between the feet and surface.
b) It is difficult to strike a match on a smooth surface because friction is needed to generate enough heat from the striking surface to light the match head. A rough surface provides more friction.
c) Pulling a boat on land is more difficult than in water because water provides less resistance (friction) than sand or rocks on a beach. The boat slides more easily through water.
d) Wet floors and roads are dangerous because water reduces the friction between shoes/tires and the surface, making it easier to slip and lose traction.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
