标题： Projecting Massive Scalar Fields to Null Infinity

摘要： 已知在渐近平坦的时空中的null infinity不能作为质量实标量场的初始值面。 利用双曲面上调和分析的工具以及波算子的全局范数估计，我们表明至少在闵可夫斯基时空中可以克服这种障碍。 因此，我们将克莱因-戈登运动方程在null infinity上的数据投影到范数有限的解上，并最终将其解释为边界自由场理论中的内容。 显示英文摘要

摘要： It is known that, in an asymptotically flat spacetime, null infinity cannot act as an initial-value surface for massive real scalar fields. Exploiting tools proper of harmonic analysis on hyperboloids and global norm estimates for the wave operator, we show that it is possible to circumvent such obstruction at least in Minkowski spacetime. Hence we project norm-finite solutions of the Klein-Gordon equation of motion in data on null infinity and, eventually, we interpret them in terms of boundary free field theory.
