On Twistor Almost Complex Structures
Michel Cahen, Simone Gutt, John Rawnsley
In this paper we look at the question of integrability, or not, of the two natural almost complex structures defined on the twistor space of an even-dimen…
Symplectic Dirac Operators and Mpc-structures
Michel Cahen, Simone Gutt, John Rawnsley
Given a symplectic manifold admitting a metaplectic structure, and choosing a positive -compatible almost complex structure and a linear connection preservi…
Topology, and (in)stability of non-Abelian monopoles
Peng-Ming Zhang, Peter A. Horvathy, John Rawnsley
The stability problem of non-Abelian monopoles with respect to "Brandt-Neri-Coleman type" variations reduces to that of a pure gauge theory on the two-sphere. Each topological sect…
Transitive Subgroups of Transvections Acting on Some Symplectic Symmetric Spaces of Ricci Type
Michel Cahen, Simone Gutt, Amin D. Malik +1
Symmetric symplectic spaces of Ricci type are a class of symmetric symplectic spaces which can be entirely described by reduction of certain quadratic Hamiltonian systems in a symp…
Monopole-charge instability
P. A. Horvathy, L. O'Raifeartaigh, J. H. Rawnsley
For monopoles with nonvanishing Higgs potential it is shown that with respect to "Brandt-Neri-Coleman type" variations (a) the stability problem reduces to that of a pure gauge the…
Affine connections with W=0
Francis Burstall, John Rawnsley
For a torsionless connection on the tangent bundle of a manifold M the Weyl curvature W is the part of the curvature in kernel of the Ricci contraction. We give a coordinate free p…
