6h	comment	totally disconnected and zero-dimensional spaces Also, you referred to the fact that the quasi-components coincide with the components in any compact Hausdorff space. Why don't you incorporate a proof of this fact into your proof? I think that would be a more substantial than simply showing the easier parts of the proof.
6h	comment	totally disconnected and zero-dimensional spaces I downvoted the answer. The standard definition of a totally disconnected space is a topological space where the components are the one-point sets. I have seen references where spaces where the quasi-components are singletons called totally separated spaces. I therefore suggest calling a space where the quasi-components are singletons totally separated spaces.

1d	comment	Examples of interesting false proofs I know for a fact that at least half of the 12 people down voted this answer because they went on my profile and looked for the question with the lowest score just so they can downvote it because they were irritated about a controversial answer that I gave to another question. And I don't see how a pun is an uninteresting example of a false proof yet cancelling out the 6's in 64/16 to get 64/16=4/1=4 is an interesting false proof.
Jun 16	comment	Examples of interesting false proofs It seems like mathematicians are completely and utterly incapable of understanding even the lowest level of humor (i.e. puns).
Jun 16	comment	Explicit form of the homeomorphism between $C[0,1]$ and $C[0,1]\setminus 0$ This does not appear to be a homework question unless I am missing something.
Jun 13	answered	Nearly all math classes are lecture+problem set based; this seems particularly true at the graduate level. What are some concrete examples of techniques other than the “standard math class” used at the Graduate level?
Jun 13	comment	on completeness of R_mn, the set of all rational functions of type (m,n) This question does not seem too trivial to me.
Jun 13	comment	Homeomorphisms and disjoint unions Since one of the spaces that Andy Putman referred to has a lot of legs and shows up in nightmares I think it is safe to call this space a monster!

Jun 7	comment	Research topics restricted to students at top universities? I am one of exceptions. I worked in a totally different area than my advisor who was also in a different country every other semester. I turned out fine I guess. I guess that I am one of those independent people.
Jun 5	comment	Property of Mrowka The property of Mrowka is not preserved under surjective images without additional hypothesis. If $X$ is any topological space, and $X_{d}$ is the discrete space with the same underlying set as $X$, then the identity map $X_{d}\rightarrow X$ is continuous and $X_{d}$ satisfies the property of Mrowka, but $X$ may not.

Jun 2	comment	When is the support of a Radon measure separable? The product $\sigma$-algebra on $[0,1]^{I}$ contains every Baire set, so since $[0,1]^{I}$ is compact we can extend this Baire measure to a Radon measure on the Borel $\sigma$-algebra in a unique way.

May 23	comment	Do operations generate well-ordered sets only? You will need a bit more than being non-decreasing in each variable since $\lfloor Log(x+1)\rfloor$ is non-decreasing in each variable.
