柯朗括号被发现是罗伊滕贝格括号的T对偶

Courant bracket found out to be T-dual to Roytenberg bracket

Ilija Ivanišević, Ljubica Davidović, Branislav Sazdović

摘要:

研究了玻色弦在坐标相关背景场中的运动。我们计算了广义电流泊松括号代数,发现它产生了柯朗括号。进一步考虑T-对偶理论,得到了对偶广义流Poisson括号代数。它产生了罗伊滕贝格括号。我们得出的结论是,与Kalb-Ramond场扭转的Courant括号是Roytenberg括号的T-对偶,具有$Q$和$R$通量。

英文摘要:

Bosonic string moving in coordinate dependent background fields is considered. We calculate the generalized currents Poisson bracket algebra and find that it gives rise to the Courant bracket. Furthermore, we consider the T-dual theory and obtain the dual generalized currents Poisson bracket algebra. It gives rise to the Roytenberg bracket. We conclude that the Courant bracket twisted with the Kalb-Ramond field is T-dual to the Roytenberg bracket, with $Q$ and $R$ flux.
