我们建立了一个算法,计算公式的CR GJMS运营商,$P^\prime$-运营商,和$Q^\prime$-曲率的CR拖拉机。当应用于无挠伪爱因斯坦接触形式时,该算法既给出了CR GJMS算子和$P^\prime$-算子的显式因式分解,又证明了$Q^\prime$-曲率是常数,该常数以韦伯斯特标量曲率的形式显式给出。我们还使用我们的算法来获得本地公式的$P^\prime$-运营商和$Q^\prime$-曲率的5维伪爱因斯坦流形。比较与马鲁加梅的制定伯恩斯-爱泼斯坦不变的积分的pseudohermitian不变产生新的见解到类的本地pseudohermitian不变的总积分是独立的选择的伪爱因斯坦接触形式。
We establish an algorithm which computes formulae for the CR GJMS operators, the $P^\prime$-operator, and the $Q^\prime$-curvature in terms of CR tractors. When applied to torsion-free pseudo-Einstein contact forms, this algorithm both gives an explicit factorisation of the CR GJMS operators and the $P^\prime$-operator, and shows that the $Q^\prime$-curvature is constant, with the constant explicitly given in terms of the Webster scalar curvature. We also use our algorithm to derive local formulae for the $P^\prime$-operator and $Q^\prime$-curvature of a five-dimensional pseudo-Einstein manifold. Comparison with Marugame's formulation of the Burns--Epstein invariant as the integral of a pseudohermitian invariant yields new insights into the class of local pseudohermitian invariants for which the total integral is independent of the choice of pseudo-Einstein contact form.
