Singular Kähler-Einstein metrics on $ \mathbb Q $-Fano compactifications of Lie groups
Description
In this paper, we prove an existence result for Kähler-Einstein metrics on $ \mathbb Q $-Fano compactifications of Lie groups by the variational method, provided their moment polytopes satisfy a fine condition. As an application, we prove that there is no $ \mathbb Q $-Fano $ {\rm SO}_4(\mathbb C) $-compactification which admits a Kähler-Einstein metric with the same volume as that of a smooth K-unstable Fano $ {\rm SO}_4(\mathbb C) $-compactification.

في هذه الورقة، نثبت وجود نتيجة لمقاييس Kähler - Einstein على $\mathbb Q $ - Fano compactifications لمجموعات LIE بالطريقة المتغيرة، بشرط أن تفي متعددات العزم بحالة دقيقة</ italic>. كتطبيق، نثبت أنه لا يوجد ضغط $\mathbb Q $- Fano ${\ rm SO }_ 4(\mathbb C )$ الذي يقبل مقياس كالر- آينشتاين بنفس حجم ضغط K - unstable Fano ${\ rm SO }_4 (\mathbb C )$.</ abstract>
