  3. Alexandre Guay, The Arbitrariness of Local Gauge Symmetry.
    This paper shows how the study of surpluses of structure is an interesting philosophical task. In particular I explore how local gauge symmetry in quantized Yang-Mills theories is the by-product of the specific dynamical structure of interaction. It is shown how in non relativistic quantum mechanics gauge symmetry corresponds to the freedom to locally define global features of gauge potentials. Also discussed is how in quantum field theory local gauge symmetry is replaced by BRST symmetry. This last symmetry is apparently (...)

  4. Alexandre Guay, Why Yang-Mills Theories?
    The elucidation of the gauge principle ``is the most pressing problem in current philosophy of physics" Redhead. This paper argues two points that contribute to this elucidation in the context of Yang-Mills theories. 1) Yang-Mills theories, including quantum electrodynamics, form a class. They should be interpreted together. To focus on electrodynamics is a mistake. 2) The essential role of gauge and BRST surplus is to provide a local theory that can be quantized and would be equivalent to the quantization of (...)

  8. Yves Gingras & Alexandre Guay (2011). The Uses of Analogies in Seventeenth and Eighteenth Century Science. Perspectives on Science 19 (2):154-191.
    The uses of analogy are ancient. It can even be argued that analogical thinking is the most basic cognitive tool humans have to move from the unknown to the known (Gentner et al. 2001). As Olson succinctly puts it, “analogies are useful when it is desired to compare an unfamiliar system with one that is better known” (Olson 1943, p. i). Analogical thinking is thus ubiquitous and found in many texts at least since Homer in Antiquity (Lloyd 1966). For example, (...)

  10. Alexandre Guay & Brian Hepburn (2009). Symmetry and its Formalisms: Mathematical Aspects. Philosophy of Science 76 (2):160-178.
    This article explores the relation between the concept of symmetry and its formalisms. The standard view among philosophers and physicists is that symmetry is completely formalized by mathematical groups. For some mathematicians however, the groupoid is a competing and more general formalism. An analysis of symmetry that justifies this extension has not been adequately spelled out. After a brief explication of how groups, equivalence, and symmetries classes are related, we show that, while it’s true in some instances that groups are (...)

This paper argues for two points that contribute to this elucidation in the context of Yang-Mills theories. 1) Yang-Mills theories, including quantum electrodynamics, form a class.
