    1. opology has reached the point where a mathematician engagedin topological research is not only justified in calling himself a topologist,but he must specify whether he is a point set topologist, differentialtopologist, algebraic topologist, or some other topological specialist.

      sub-branches of topology: - point-set topology<br /> - differential topology<br /> - algebraic topology

    1. One of the problems in approaching quantum gravity is the choice for how to best represent it mathematically. Most of quantum mechanics is algebraic in nature but gravity has a geometry component which is important. (restatement)


      This is similar to the early 20th century problem of how to best represent quantum mechanics: as differential equations or using group theory/Lie algebras?

      This prompts the question: what other potential representations might also work?

      Could it be better understood/represented using Algebraic geometry or algebraic topology as perspectives?
