2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/52097We give a method to construct Calabi-Yau metrics on G-invariant vector bundles over Kahler coset spaces G/H using supersymmetric nonlinear realizations with matter coupling. As a concrete example we discuss the CP^N model coupled with matter. The canonical line bundle is reproduced by the singlet matter and the cotangent bundle with a new non-compact Calabi-Yau metric which is not hyper-Kahler is obtained by the anti-fundamental matter.18 pages, one figureHigh Energy Physics - TheoryDifferential Geometrytext
