Interests tend to center around differential geometry.
For now, I plan on being far more active on math.stackexchange.com

When is a Riemannian metric equivalent to the flat metric on $\mathbb R^n$?
Deane: "I don't believe I've ever seen this result used for anything." If you're referencing Cartan's Theorem (the local version of Cartan-Ambrose-Hicks), then I believe it can be used to prove that any Riemannian manifold with $\nabla R = 0$ is locally isometric to a symmetric space. |

Awfully sophisticated proof for simple facts
And here I was thinking the standard proof was just the Integral Test for series convergence. |

How to respond to “I was never much good at maths at school.”
It's interesting. Pretty much everyone I know would agree that it's not a good thing when elementary school teachers tell their students that they didn't like math, either. And yet I can think of more than a handful of those same people (grad students and professors) who would have no problem telling their calculus classes that they don't like calculus, or that it's not "real" math somehow... |

“Softness” vs “rigidity” in Geometry
Funny, I would've said that when doing geometry, you either fall into algebra or analysis. In fact, it seems to me that the more "rigid" your geometry is, the more likely you are to fall into one of the sides. By contrast, "softer" geometries can rely on topology. |

Fundamental motivation for several complex variables
That's fair. In truth, I'm still rather ignorant about harmonic functions and their properties. I don't mean to suggest that reason (1) is the only reason one would care about them, but simply that it's a primary reason that I do (again, given my ignorance). |

How to escape the inclination to be a universalist or: How to learn to stop worrying and do some research.
"Maybe the bred desire that you mention is (or is related to) the emphasis on 'theory building'. Yes, theory building is great, but I personally see it through the lens of problem solving." Okay, but what if one is far more interested in theory building than problem solving, or if theory-building IS the lens by which one views things? |

"What makes some of you think the 'math' people learned in school is 'not real'?" Just for that one line I would upvote your comment ten times if I could. For me it is extremely refreshing to hear a professional mathematician question that line. Thank you for that. |

How should one present curl and divergence in an undergraduate multivariable calculus class?
To be pedantic, I think technically it's $\text{curl} = \sharp \circ \ast \circ d \circ \flat$, but no matter. |

Meaning of \Subset notation
I have seen $A \Subset B$ mean that the (topological) closure of $A$ is contained in $B$, but I'm sure there are plenty of other uses as well. Could you perhaps provide some context? |

Memorizing theorems
+1 for the first sentence. Memorization is certainly not a substitute for understanding -- and really, who would ever claim that it is? -- but it's sometimes just so useful! Especially in areas like real analysis where theorems can have multiple hypotheses and omitting even one of them can render the theorem false (think Dini's Theorem), sometimes it just saves time and stress to sit down one day and memorize it. Also, the "modes of convergence" diagram is wonderful. |
