Real symplectic formulation of local special geometry

Sergio Ferrara, Oscar Macia

We consider a formulation of local special geometry in terms of Darboux special coordinates $P^{I} = (p^{i}, q_{i})$ , $I = 1, ..., 2 n$ . A general formula for the metric is obtained which is man…

Observations on the Darboux coordinates for rigid special geometry

Sergio Ferrara, Oscar Macia

We exploit some relations which exist when (rigid) special geometry is formulated in real symplectic special coordinates $P^{I} = (p^{Λ}, q_{Λ}), I = 1, ..., 2 n$ . The central role of the real $…

Contractions of sigma models and integration of massive modes

M. A. Lledo, O. Macia

We show how the integration of massive modes after a spontaneous symmetry breaking in a sigma model can often be interpreted as a contraction, induced by a group contraction, of th…
