Chen-Te Ma, Che-Min Shen

摘要:

双场论(DFT)为同时具有动量和缠绕激励的无质量闭弦场论提供了一个明显的T-对偶公式。规范对称性由广义李导数定义,它是柯朗括号的扩展。本文研究了DFT的FRW(Friedmann-Robertson-Walker)和二重球对称度规的性质。

英文摘要:

Double field theory (DFT) offers a manifest T-duality formulation for massless closed string field theory with both momentum and winding excitation. The gauge symmetry is defined by the generalized Lie derivative which is the extension of the Courant bracket. In this work, we solve and study the properties of FRW (Friedmann- Robertson-Walker) and doubled spherically symmetric metric of DFT.
