Alexander Alexandrov

AI总结:

本研究构建了带简单分歧点的局部谱曲线的Chekhov-Eynard-Orantin拓扑递归配分函数的三次切接算子描述,涵盖所有半单上同调场论配分函数,导出拓扑递归的代数版本,还推导了N族Virasoro约束并证明其加形变维数约束可推出切接描述。

摘要:

我们针对具有简单分歧点的局部谱曲线,构建了Chekhov-Eynard-Orantin拓扑递归配分函数的三次切接算子描述。这类描述尤其涵盖所有半单上同调场论的配分函数。切接描述导出了拓扑递归的代数版本。针对同一配分函数,我们还推导了N族Virasoro约束,并证明这些约束辅以形变维数约束,可推导出切接描述。

英文摘要:

We construct a cubic cut-and-join operator description for the partition function of the Chekhov-Eynard-Orantin topological recursion for a local spectral curve with simple ramification points. In particular, this class contains partition functions of all semi-simple cohomological field theories. The cut-and-join description leads to an algebraic version of topological recursion. For the same partition functions we also derive N families of the Virasoro constraints and prove that these constraints, supplemented by a deformed dimension constraint, imply the cut-and-join description.
