我们考虑了（n+2）维时空中自引力n膜的碰撞。我们表明，有一个几何约束，可以表示为一个简单的总和规则的角度之间的膜和干预时空区域的洛伦兹助推器的特征。这个约束可以被重新解释为碰撞时的能量守恒或动量守恒。
We consider the collision of self-gravitating n-branes in a (n+2)-dimensional spacetime. We show that there is a geometrical constraint which can be expressed as a simple sum rule for angles characterizing Lorentz boosts between branes and the intervening spacetime regions. This constraint can then be reinterpreted as either energy or momentum conservation at the collision.
