Dimensional Reduction and Quantum Gravity

  • Jonas Mureika

摘要

Dimensional reduction is a common feature of disparate candidates for a final theory of quantum gravity. This paper will review key aspects of lower dimensional gravity, and discuss a number of mechanisms through which dimensional reduction might occur, as well as their phenomenology and observational prospects.
