Everettian Rationality: defending Deutsch's approach to probability in the Everett interpretation
An analysis is made of Deutsch's recent claim to have derived the Born rule from decision-theoretic assumptions. It is argued that Deutsch's proof must be understood in the explicit context of theExpand

Many Worlds: an Introduction 1. WHY MANY WORLDS? 1. Decoherence and Ontology 2. Quasiclassical Realms 3. Macroscopic Superpositions, Decoherent Histories, and the Emergence of HydrodynamicalExpand
Quantum Probability from Subjective Likelihood: improving on Deutsch's proof of the probability rule

  • Computer Science, Physics
  • 18 December 2003
TLDR
The basic ideas behind the proof are those presented in Deutsch's recent proof of the probability rule, but the proof is simpler and proceeds from weaker decision-theoretic assumptions, which makes it easier to discuss the conceptual ideas involved, and to show that they are defensible. Expand
Empirical Consequences of Symmetries
  • H. Greaves, D. Wallace
  • Mathematics, Physics
  • The British Journal for the Philosophy of Science
  • 18 November 2011
It is widely recognized that ‘global’ symmetries, such as the boost invariance of classical mechanics and special relativity, can give rise to direct empirical counterparts such as the Galileo-shipExpand
In Defence of Naiveté: The Conceptual Status of Lagrangian Quantum Field Theory
  • D. Wallace
  • Mathematics, Computer Science
  • Synthese
  • 1 July 2006
TLDR
The analysis covers renormalisation and infinities, inequivalent representations, and the concept of localised states; the conclusion is that Lagrangian QFT is a perfectly respectable physical theory, albeit somewhat different in certain respects from most of those studied in foundational work. Expand
Everett and structure
I address the problem of indefiniteness in quantum mechanics: the problem that the theory, without changes to its formalism, seems to predict that macroscopic quantities have no definite values. TheExpand
Worlds in the Everett interpretation
This is a discussion of how we can understand the world-view given to us by the Everett interpretation of quantum mechanics, and in particular the role played by the concept of `world'. The viewExpand
Quantum Probability and Decision Theory, Revisited
An extended analysis is given of the program, originally suggested by Deutsch, of solving the probability problem in the Everett interpretation by means of decision theory. Deutsch's own proof isExpand
Quantum Mechanics on Spacetime I: Spacetime State Realism
  • D. Wallace, C. Timpson
  • Philosophy, Physics
  • The British Journal for the Philosophy of Science
  • 30 July 2009
What ontology does realism about the quantum state suggest? The main extant view in contemporary philosophy of physics is wave-function realism. We elaborate the sense in which wave-function realismExpand
