标题： Lorentz Transformations from Reflections:Some Applications

摘要： 我们通过展示两个例子并提及第三个例子指出，有时将洛伦兹变换视为由超平面或直线反射生成是有用的。 其中一个例子涉及构建连接两个给定四向量的 boost，另一个例子涉及 V. Moretti 关于正时洛伦兹矩阵极分解的闵可夫斯基几何理解。 显示英文摘要

摘要： We point out, by exhibiting two examples and mentioning a third one, that it is sometimes useful to consider Lorentz transformations as generated from hyperplane or line reflections. One example concerns the construction of boosts linking two given 4-vectors, the other one concerns the Minkowski geometric understanding of V. Moretti's polar decomposition of orthochronous Lorentz matrices.
