Weyl结构的Q曲率与Poincaré度量

Q-curvature of Weyl structures and Poincaré metrics

Kengo Hirachi, Christian Lübbe, Yoshihiko Matsumoto

摘要:

研究了渐近双曲流形上Weyl结构的渐近狄利克雷问题.通过体边界对应,或者更准确地说,通过庞加莱度量的费曼-格雷厄姆定理,这导致了布兰森的$Q$ -曲率概念到偶维共形流形上的外尔结构的自然扩张。

英文摘要:

We study an asymptotic Dirichlet problem for Weyl structures on asymptotically hyperbolic manifolds. By the bulk-boundary correspondence, or more precisely by the Fefferman-Graham theorem on Poincaré metrics, this leads to a natural extension of the notion of Branson's $Q$-curvature to Weyl structures on even-dimensional conformal manifolds.
