It was proved by Paul that the $K$-energy of $(X,\\omega_{FS}|_{X})$ restricted to the Bergman metrics is bounded from below if and only if the pair of (rescaled) Chow/Hurwitz forms of $X$ is semistable. In this paper, we provide a necessary and sufficient condition for a given smooth toric variety $X_P$ to be semistable of pairs with respect to $\\mathcal O_{X_P}(i)$ for a positive integer $i$. Applying this result to a smooth polarized toric variety $(X_P, L_P)$, we prove that $(X_P, L_P)$ is asymptotically semistable of pairs if and only if it is K-semistable for toric degenerations.", "revisions": [ { "version": "v1", "updated": "2024-01-04T00:42:40.000Z" } ], "analyses": { "subjects": [ "51M20", "14M25", "53C55" ], "keywords": [ "projective toric varieties", "semistability", "smooth polarized toric variety", "smooth linearly normal projective variety", "smooth toric variety" ], "note": { "typesetting": "TeX", "pages": 27, "language": "en", "license": "arXiv", "status": "editable" } } }
