Ogievetsky和Polubarinov通过排除低自旋发现的爱因斯坦引力（在闵可夫斯基背景下）的2参数族大质量变体也可以使用万有耦合导出。狄拉克-伯格曼约束动力学分析似乎还没有为这些理论，弗罗因德-马赫什瓦里-舍恩贝格特殊情况，或任何其他大规模的重力超过线性水平处理的马兹班，怀汀和货车大坝。在这里，狄拉克-伯格曼装置被应用于这些理论。关于正能量的问题，我想谈几点。作为双度规，大质量引力有一个因果关系之谜，但它似乎可以通过引入和明智地使用规范自由来解决。
The 2-parameter family of massive variants of Einsteins gravity (on a Minkowski background) found by Ogievetsky and Polubarinov by excluding lower spins can also be derived using universal coupling. A Dirac-Bergmann constrained dynamics analysis seems not to have been presented for these theories, the Freund-Maheshwari-Schonberg special case, or any other massive gravity beyond the linear level treated by Marzban, Whiting and van Dam. Here the Dirac-Bergmann apparatus is applied to these theories. A few remarks are made on the question of positive energy. Being bimetric, massive gravities have a causality puzzle, but it appears soluble by the introduction and judicious use of gauge freedom.
