Yang-Mills Instantons with Lorentz Violation
An analysis is performed of instanton configurations in pure Euclidean
Yang-Mills theory containing small Lorentz-violating perturbations that
maintain gauge invariance. Conventional topological arguments are used to show
that the general classification of instanton solutions involving the
topological charge is the same as in the standard case. Explicit solutions are
constructed for general gauge invariant corrections to the action that are
quadratic in the curvature. The value of the action is found to be unperturbed
to lowest order in the Lorentz-violating parameters.Comment: 16 page
SU(3) monopoles and their fields
Some aspects of the fields of charge two SU(3) monopoles with minimal
symmetry breaking are discussed. A certain class of solutions look like SU(2)
monopoles embedded in SU(3) with a transition region or ``cloud'' surrounding
the monopoles. For large cloud size the relative moduli space metric splits as
a direct product AH\times R^4 where AH is the Atiyah-Hitchin metric for SU(2)
monopoles and R^4 has the flat metric. Thus the cloud is parametrised by R^4
which corresponds to its radius and SO(3) orientation. We solve for the
long-range fields in this region, and examine the energy density and rotational
moments of inertia. The moduli space metric for these monopoles, given by
Dancer, is also expressed in a more explicit form.Comment: 17 pages, 3 figures, latex, version appearing in Phys. Rev.
Franchises lost and gained: post-coloniality and the development of womenâs rights in Canada
The Canadian constitution is to some extent characterised by its focus on equality, and in particular gender equality. This development of womenâs rights in Canada and the greater engagement of women as political actors is often presented as a steady linear process, moving forwards from post-enlightenment modernity. This article seeks to disturb this âdiscourse of the continuous,â by using an analysis of the pre-confederation history of suffrage in Canada to both refute a simplistic linear view of womenâs rights development and to argue for recognition of the Indigenous contribution to the history of womenâs rights in Canada.
The gain of franchise and suffrage movements in Canada in the late nineteenth and early twentieth century are, rightly, the focus of considerable study (Pauker 2015), This article takes an alternative perspective. Instead, it examines the exercise of earlier franchises in pre-confederation Canada. In particular it analyses why franchise was exercised more widely in Lower Canada and relates this to the context of the removal of franchises from women prior to confederation
