Gravity and Gauge
gravity gauge theory topological quantum field theory Chern-Simons theory
2016/6/15
Philosophers of physics and physicists have long been intrigued by the analogies and disanalogies between gravitational theories and (Yang-Mills-type) gauge theories. Indeed, repeated attempts to coll...
Some Remarks on Rovelli's "Why Gauge?"
philosophy of gauge theory Yang-Mills physical significance of gauge-dependence
2016/6/15
Rovelli's "Why Gauge?" offers a parable to show that gauge-dependent quantities have a modal and relational physical significance. We subject the morals of this parable to philosophical scrutiny and a...
Why Gauge?
Gauge Symmetry
2016/6/15
The world appears to be well described by gauge theories; why? I suggest that gauge is more than mathematical redundancy. Gauge-dependent quantities can not be predicted, but there is a sense in which...
A First Class Constraint Generates Not a Gauge Transformation,But a Bad Physical Change:The Case of Electromagnetism
empirical equivalence gauge freedom quantum gravity problem of time
2016/6/15
In Dirac-Bergmann constrained dynamics, a first-class constraint typically does not _alone_ generate a gauge transformation. By direct calculation it is found that each first-class constraint in Maxwe...
The standard U(1) “gauge principle” or “gauge argument” produces an exact potential A=dλ and a vanishing field F=ddλ=0. Weyl has his own gauge argument, which is sketchy, archaic and hard to follow; b...

Philosophers of physics and physicists have long been intrigued by the analogies and disanalogies between gravitational theories and (Yang-Mills-type) gauge theories. Indeed, repeated attempts to col-...
Simultaneity,Convention,and Gauge Freedom
simultaneity convention special relativity gauge freedom hole argument
2016/5/31
As is well known from Einstein (1905) the choice of a criterion for distant simultaneity is equivalent to stipulating one-way speeds for the transit of light. It is shown that any choice of non-standa...
On emergence in gauge theories at the 't Hooft limit
Emergence gauge theories the 't Hooft limit quantum chromodynamics supersymmetry planarity integrability
2016/5/27
Quantum field theories are notoriously difficult to understand, physically as well as philosophically. The aim of this paper is to contribute to a better conceptual understanding of gauge quantum fiel...
Logic of gauge
Weyl gauge theory Yang-Mills connections
2016/5/27
The logic of gauge theory is considered by tracing its development from general relativity to Yang-Mills theory, through Weyl's two gauge theories.
Shortening the gauge argument
gauge argument Lagrangian symmetries local and global transformations
2016/5/27
The "gauge argument" is often used to `deduce' interactions from a symmetry requirement. A transition---whose justification can take some effort---from global to local transformations is typically mad...

Gauge-Invariant Localization of Infinitely Many Gravitational Energies from All Possible Auxiliary Structures
conservation laws localization invariance infinite-component gravitational energy
2009/6/11
The problem of finding a covariant expression for the distribution and conservation of gravitational energy-momentum dates to the 1910s. A suitably covariant infinite-component localization is display...
Non-locality and gauge freedom in Deutsch and Hayden'sformulation of quantum mechanics
non-locality gauge freedom
2008/4/22
Deutsch and Hayden have proposed an alternative formulation of quantum mechanics which is completely local. We argue that their proposal must be understood as having a form of `gauge freedom' accordin...
Classically, a gauge potential was merely a convenient device for generating a corresponding gauge field. Quantum-mechanically, a gauge potential lays claim to independent status as a further feature ...
What is the significance of gauge freedom? This paper makes a start on answering this and other interpretative questions about classical and quantum gauge theories by situating classical gauge freedom...
