迈向引力的非对易版本
Towards a noncommutative version of Gravitation
摘要:
阿兰·康纳斯的非对易理论导致了一个有趣的模型,包括粒子物理学的标准模型和欧几里得引力。尽管如此,引力部分的双曲线版本对于进行物理预测是必要的,但它仍在研究中。我们将介绍从黎曼几何推广到洛伦兹几何的困难,并讨论关键思想和当前的尝试。
英文摘要:
Alain Connes' noncommutative theory led to an interesting model including both Standard Model of particle physics and Euclidean Gravity. Nevertheless, an hyperbolic version of the gravitational part would be necessary to make physical predictions, but it is still under research. We shall present the difficulties to generalize the model from Riemannian to Lorentzian Geometry and discuss key ideas and current attempts.
