Also, by using Donaldson's quantization link between the infinite and finite dimensional G.I.T quotients that describe moduli spaces of varieties, we define a natural sequence of Kaehler metrics. We prove that the sequence converges to the Weil-Petersson metric. We also develop an algorithm that numerically approximates such metrics, and hence the Weil-Petersson metric itself. Explicit examples are provided on a family of Calabi-Yau Quintic hypersurfaces in CP^4. The scope of our second algorithm is much broader; the same techniques can be used to approximate metrics on null spaces of Dirac operators coupled to Hermite Yang-Mills connections.", "revisions": [ { "version": "v2", "updated": "2012-07-09T02:18:56.000Z" } ], "analyses": { "keywords": [ "moduli spaces", "numerical weil-petersson metrics", "calabi-yau manifolds", "hermite yang-mills connections", "donaldsons quantization link" ], "publication": { "doi": "10.1016/j.geomphys.2015.02.018" }, "note": { "typesetting": "TeX", "pages": 28, "language": "en", "license": "arXiv", "status": "editable", "inspire": 825342, "adsabs": "2009arXiv0907.1387K" } } }
