Unambiguous spin-gauge formulation of canonical general relativity with conformorphism invariance
Charles H. -T. Wang
We present a parameter-free gauge formulation of general relativity in terms of a new set of real spin connection variables. The theory is constructed by extending the phase space…
Strength of convergence in the orbit space of a transformation group
Robert Archbold, Astrid an Huef
Let (G, X) be a second-countable transformation group with G acting freely on X. It is shown that measure-theoretic accumulation of the action and topological strength of convergen…
Finite-size effects on open chaotic advection
Rafael Dias Vilela, Alessandro P. S. de Moura, Celso Grebogi
We study the effects of finite-sizeness on small, neutrally buoyant, spherical particles advected by open chaotic flows. We show that, when projected onto configuration space, the…
Relative Kazhdan--Lusztig cells
Meinolf Geck
In this paper, we study the Kazhdan--Lusztig cells of a Coxeter group in a ``relative'' setting, with respect to a parabolic subgroup . This relies on a factor…
