The Principle of Symmetric Criticality in General Relativity
Mark E. Fels, Charles G. Torre
We consider a version of Palais' Principle of Symmetric Criticality (PSC) that is applicable to the Lie symmetry reduction of Lagrangian field theories. PSC asserts that, given a g…
Extension of Fill's perfect rejection sampling algorithm to general chains (Extended abstract)
James Allen Fill, Motoya Machida, Duncan J. Murdoch +1
We provide an extension of the perfect sampling algorithm of Fill (1998) to general chains, and describe how use of bounding processes can ease computational burden. Along the way,…
Extension of Fill's perfect rejection sampling algorithm to general chains
James Allen Fill, Motoya Machida, Duncan J. Murdoch +1
By developing and applying a broad framework for rejection sampling using auxiliary randomness, we provide an extension of the perfect sampling algorithm of Fill (1998) to general…
Group Invariant Solutions in Mathematical Physics and Differential Geometry
I. M. Anderson, M. E. Fels, C. G. Torre
This is a brief overview of our work on the theory of group invariant solutions to differential equations. The motivations and applications of this work stem from problems in diffe…
