辛正交Penner模型

The Symplectic-Orthogonal Penner Models

Mohammad Dalabeeh, Noureddine Chair

摘要:

给出了以$2g$为标志点的实代数曲线的模空间的轨道欧拉特征线的生成函数.结果表明,辛模型和正交Penner模型在连续极限下的自由能几乎相同,结构为$F^{SP/SO}(μ)=1/2F(μ)\mp F^{NO}(μ)$,其中$F(μ)$为Penner自由能,$F^{NO}(μ)$为不可定向表面的自由能贡献.这两个模型与Penner模型具有相同的临界点。

英文摘要:

The generating function for the orbifold Euler characteristic of the moduli space of real algebraic curves of genus $2g$ (locally orientable surfaces) with $n$ marked points $χ^r(\mathfrak{M}_{2g,n})$, is identified with a simple formula. It is shown that the free energy in the continuum limit of both the symplectic and the orthogonal Penner models are almost identical, with the structure $F^{SP/SO}(μ)=1/2F(μ)\mp F^{NO}(μ)$, where $F(μ)$ is the Penner free energy and $F^{NO}(μ)$ is the free energy contributions from the non-orientable surfaces. Both of these models have the same critical point as the Penner model.
