2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/105954We develop a method for relating the boundary effective action associated with an orbifold of the D+1 dimensional theory of a p-form field to D dimensional fluxed Chern-Simons type of terms. We apply the construction to derive from twelve dimensions the Chern-Simons terms of the eleven dimensional supergravity theory in the presence of flux.Minor corrections madeHigh Energy Physics - Theorytext
