On Symplectic Reduction in Classical Mechanics
Jeremy Butterfield
This paper expounds the modern theory of symplectic reduction in finite-dimensional Hamiltonian mechanics. This theory generalizes the well-known connection between continuous symm…
On Symmetry and Conserved Quantities in Classical Mechanics
Jeremy Butterfield
This paper expounds the relations between continuous symmetries and conserved quantities, i.e. Noether's ``first theorem'', in both the Lagrangian and Hamiltonian frameworks for cl…
Between Laws and Models: Some Philosophical Morals of Lagrangian Mechanics
Jeremy Butterfield
I extract some philosophical morals from some aspects of Lagrangian mechanics. (A companion paper will present similar morals from Hamiltonian mechanics and Hamilton-Jacobi theory.…
On Hamilton-Jacobi theory: its geometry and relation to pilot-wave theory
Jeremy Butterfield
This paper gives a technically elementary treatment of some aspects of Hamilton-Jacobi theory, especially in relation to the calculus of variations. The second half of the paper de…
A Topos Perspective on the Kochen-Specker Theorem: IV. Interval Valuations
J. Butterfield, C. J. Isham
We extend the topos-theoretic treatment given in previous papers of assigning values to quantities in quantum theory. In those papers, the main idea was to assign a sieve as a part…
Some Worlds of Quantum Theory
Jeremy Butterfield
This paper assesses the Everettian approach to the measurement problem, especially the version of that approach advocated by Simon Saunders and David Wallace. I emphasise conceptua…
