摘要

在[Rie08]中，第二作者将齐次空间G=P的Landau-Ginzburg模型定义为Langlands对偶群的一个子变体上的正则函数。在本文中，我们将奇维二次型Q2m 1重新表述为射影空间p2m = P(H (Q2m 1;C))中特定反正则因子的补X上的正则函数Wt。实际上，我们用

A Comparison of Landau-Ginzburg Models for Odd Dimensional Quadrics

In [Rie08], the second author dened a Landau-Ginzburg model for homogeneous spaces G=P , as a regular function on an ane subvariety of the Langlands dual group. In this paper, we reformulate this LG model in the case of the odd-dimensional quadric Q2m 1 as a regular function Wt on the complement X of a particular anticanonical divisor in the projective space P 2m = P(H (Q2m 1;C) ). In fact, we express Wt in
