论文摘要
我们考虑一个$ O（D，D; \ Mathbb {Z}）$在自由理论级别上对双场理论的不变性变形。我们在$ r^{1，n-1} \ times t^{d} $上研究kaluza-klein减少，并为每个螺旋模式得出对角度的二阶操作。施加了幽灵和tachyon的缺乏，我们获得了一类一致性条件，其中包括双重田地理论中众所周知的弱约束，作为一种特殊情况。因此，我们找到了$ o的两参数集（d，d; \ mathbb {z}）$不变的fierz-pauli巨大的重力理论。
We consider an $O(d,d;\mathbb{Z})$ invariant massive deformation of double field theory at the level of free theory. We study Kaluza-Klein reduction on $R^{1,n-1} \times T^{d}$ and derive the diagonalized second order action for each helicity mode. Imposing the absence of ghosts and tachyons, we obtain a class of consistency conditions which include the well known weak constraint in double field theory as a special case. Consequently, we find two-parameter sets of $O(d,d;\mathbb{Z})$ invariant Fierz-Pauli massive gravity theories.
