This Differential geometry related article is a stub. Justin, You should start with an advanced undergraduate course in geometry, specifically one dealing with differentiable manifolds.
Modern Geometry | Not Even Wrong
However, in general, one problem many physicists have with talking to the general pure mathematical audience today is that they assume too much knowledge of differential equations.
He makes some effort to relate differential geometry to physics. Differential geometry String theory Differential geometry stubs String theory stubs.
September 5, at 4: This is a story both physicists and mathematicians should know about. September 6, at While I think he is not right, there is a grain of truth in his remark.

gil,ey What would be nice is a review where eguchu can really see the power of sophisticated methods in doing calculations.
To get spinors, one way is to use principal gilkwy September 13, at 5: Even a short time later, people forget their beginners mind-set and thus what made the subject counter-intuitive enough to need a motivated pitch so that the new tools would be adopted. Home Frequently Asked Questions. I wish more beginning students would go back to look at those special moments where everything suddenly changed.
In addition, any geometer should know about how geometry gets used in these two areas of physics. Strangely, this old book or set of notes seemed much clearer and better motivated than the treatment in the leading contemporary pedagogical janson of the time by Robin Harthshorne. September 5, at 2: I also wonder if the original paper might benefit from being longer [neglecting problems and the like] for the same haneon or, more precisely, the same length for less material.
The Eguchi—Hanson metric is the prototypical example of a gravitational instanton. Kobayashi and Nomizu is a beautiful book which I now appreciate but I found it frustrating when I was learning the subject and it took me many years to understand why — it is deceptive because they prove some of the most beautiful theorems in 2 lines.
September 4, at 6: The holonomy group of this 4-real-dimensional manifold is SU 2as it is for a Calabi-Yau K3 surface. What one perhaps needs is some sort of quantum fibre bundles. Certain types of K3 surfaces can be approximated as a combination of several Eguchi—Hanson metrics. September 4, at 5: The real work goes into many pages of definitions which are given almost without motivation. Then, mysteriously, the old text is forgotten as new pedagogical texts attempt to reach students rather than professors.
September 5, at 8: As ideas get more solidified, notations sometimes improve, and make things clearer. You could just immediately start building. You can help Wikipedia by expanding it. Proudly powered by WordPress.
In addition, I just took a look again at the review article by Eguchi, Gilkey and Hanson see here or here from which I first learned a lot of this material. To give some random examples, consider localization in non-Abelian gauged linear sigma models, the Kapustin Witten story or bundle constructions for heterotic models. September 7, at 9: If you are comfortable with Riemannian geometry, GR is not hard. September 4, at 4: Retrieved from ” https: Never mind limits or all that. It seems to cover gikey kinds of things you want to touch upon connections on principal hansoh.
For that reason, I think results are somewhat mixed, as with any pedagogical text.
In general though, I think the power of the abstract geometrical formalism is that it tells you what the general coordinate independent features of solutions will be. I am an extreme example, but all my knowledge of differential equations comes from teaching the standard first undergraduate course on linear ODEs, and I learned that by TAing the course, not by ever having taken it.
Steve Bryson sent me another excellent suggestion for a book covering these topics, aimed at the physical applications: September 12, at 3: While the metric is generally attributed to the bilkey Eguchi and Hanson,  it was actually discovered independently by the mathematician Eugenio Calabi  around the same time.
This page was last edited on 2 Novemberat For some reason, in these situations, what gets written as a pitch or a sales job is often far clearer than what will later be written to introduce the toolkit to future students. Dear all, Hanzon remember the remark by Weinberg in his beautiful book about GR etc.
But, in any particular case, to actually ggilkey you may need to choose coordinates, better, coordinates adapted to eyuchi problem. If pressed, I might be able to recall the solution to the heat equation. I have always liked the tensor calculus centipede being intoxicated by a plethora of indices.
