这篇文章对最近试图为非微扰弦理论找到一个统一框架的尝试给出了个人的看法，特别强调了超引力的隐藏对称性及其在这一奋进中可能发挥的作用。从这个角度讨论了d = 11的超引力的一个扩展的切空间对称性SO（1，2）× SO（16）的重新表述，以及构造SO（1，1）× SO（16）甚至SO（1，1）+ × ISO（16）切空间对称性的进一步版本的可能性。在“第三次量子化”之后，降维的最大超引力可能与降维的最大超对称SU（∞）杨米尔斯理论在这一统一中起着同样重要的作用。
This contribution gives a personal view on recent attempts to find a unified framework for non-perturbative string theories, with special emphasis on the hidden symmetries of supergravity and their possible role in this endeavor. A reformulation of d = 11 supergravity with enlarged tangent space symmetry SO(1, 2) × SO(16) is discussed from this perspective, as well as an ansatz to construct yet further versions with SO(1, 1)× SO(16) and possibly even SO(1, 1)+ × ISO(16) tangent space symmetry. It is suggested that upon “third quantization”, dimensionally reduced maximal supergravity may have an equally important role to play in this unification as the dimensionally reduced maximally supersymmetric SU(∞) Yang Mills theory.
