M/弦论中黑膜的U-对偶蕴涵

Implication of U-duality for black branes in M/string theory

Samrat Bhowmick

摘要:

M-理论的U-对偶性和弦论的S-对偶性和T-对偶性可以用来研究各种黑膜解。我们在这里探讨这个想法的一些方面。这种对称性可以用来得到黑膜度规的各个分量之间的关系。这些关系反过来又给出了能量-动量张量的各个分量之间的关系。我们证明了,利用这些关系,在不知道形域的显式形式的情况下,我们可以得到黑膜解。这些特征以前在M理论的背景下进行了研究。在这里,我们在弦论(II型超引力)中广泛地研究了它们。我们还表明,这一提法工程异国情调的膜。我们给出了一个例子的时间依赖系统,这种方法是必不可少的。

英文摘要:

U-duality symmetry of M-theory and S and T-duality of string theory can be used to study various black branes solutions. We explore some aspect of this idea here. This symmetry can be used to get relations among various components of the metric of the black brane. These relations in turn give relations among various components of the energy-momentum tensor. We show that, using these relations, without knowing the explicit form of form fields, we can get the black brane solutions. These features were studied previously in the context of M-theory. Here we extensively studied them in string theory (type II supergravity). We also show that this formulation works for exotic branes. We give an example of a time-dependent system where this method is essential.
