超流形上Poisson-Lie T-对偶西格玛模型的弦宇宙学

String cosmology from Poisson-Lie T-dual sigma models on supermanifolds

A. Eghbali, A. Rezaei-Aghdam

摘要:

我们将流形上Poisson-Lie T-对偶西格玛模型的形式推广到了超流形上。在这方面,我们建立了耦合到两个费米子场的李超群C^3及其对偶(A_1,1 + 2A)^0_(1,0,0)上的1+1维弦宇宙学模型。然后,我们求解了模型的运动方程,并证明了原模型及其对偶模型的度量存在本质奇异性。

英文摘要:

We generalize the formulation of Poisson-Lie T-dual sigma models on manifolds to supermanifolds. In this respect, we formulate 1+1 dimensional string cosmological models on the Lie supergroup C^3 and its dual (A_1,1 + 2A)^0_(1,0,0), which are coupled to two fermionic fields. Then, we solve the equations of motion of the models and show that there is a essential singularity for the metric of the original model and its dual.
