Internal symmetries in Kaluza-Klein models
Joao Baptista
The usual approach to Kaluza-Klein considers a spacetime of the form and identifies the isometry group of the internal vacuum metric, , with the gauge group i…
Higher-dimensional routes to the Standard Model fermions
Joao Baptista
In the old spirit of Kaluza-Klein, we consider a spacetime of the form , where is the Lie group equipped with a left-invariant metric that is…
Higher-dimensional routes to the Standard Model bosons
Joao Baptista
In the old spirit of Kaluza-Klein, we consider a spacetime of the form , where is the Lie group equipped with a left-invariant metric that is…
Vortices as degenerate metrics
J. M. Baptista
We note that the Bogomolny equation for abelian vortices is precisely the condition for invariance of the Hermitian-Einstein equation under a degenerate conformal transformation. T…
On the L^2-metric of vortex moduli spaces
J. M. Baptista
We derive general expressions for the Kaehler form of the L^2-metric in terms of standard 2-forms on vortex moduli spaces. In the case of abelian vortices in gauged linear sigma-mo…
Non-abelian vortices, Hecke modifications and singular monopoles
J. M. Baptista
In this note we show that for the group G = U(N) the space of Hecke modifications of a rank N vector bundle over a Riemann surface C coincides with the moduli space of solutions of…
