我们研究了维数至少为2的Legendrian子流形的clasp移动对伪全纯曲线模空间的影响,这些伪全纯曲线对Chekanov-Eliashberg代数的微分有贡献。作为应用,我们计算了维数至少为2的扭转球Λ_k的Chekanov-Eliashberg代数的微分。此外,我们从P×ℝ中任意水平可位移的Legendrian Λ构造了无限族Legendrian 𝒯(Λ,k),使得𝒯(Λ,k)的Chekanov-Eliashberg代数容许一个增广,而当k足够大时,𝒯(Λ,k)在P×ℝ的辛化中没有消失Maslov类的正合嵌入Lagrangian填充。
英文摘要
We investigate the effect of the clasp move of Legendrian submanifolds of dimension at least two on the moduli spaces of pseudo-holomorphic curves that contribute to the differential of the Chekanov-Eliashberg algebra. As an application, we compute the differential of Chekanov-Eliashberg algebra of twist spheres $Λ_k$ of dimension at least two. Moreover, we construct an infinite family of Legendrians $\mathcal{T}(Λ,k)$ from any horizontally displaceable Legendrian $Λ$ in $P\times\mathbb{R}$, such that the Chekanov-Eliashberg algebra of $\mathcal{T}(Λ,k)$ admits an augmentation, while $\mathcal{T}(Λ,k)$ has no exact embedded Lagrangian filling of vanishing Maslov class in the symplectization of $P\times \mathbb{R}$ for sufficiently large $k$.
