Currently a post-doc at Penn, was a grad-student at Rutgers. Here are some papers, some software, and a seminar.

comment Which journals publish applied mathematics with mostly pure mathematics content?
I had exactly the same question two years ago with this paper: aimsciences.org/journals/pdfs.jsp?paperID=10624&mode=full -- I've been extremely impressed with the relatively new Journal of Computational Dynamics. I experienced high quality of anonymous reviews, a relatively quick turnaround time, and a top-notch theory-savvy editorial board. That being said, I wish they'd go open access and lose the comic sans from their website.

@petermay I have it on good authority that the jokes are excruciating!

Is it too late to suggest a new "ask-may" tag?

comment Graduate Schools for Graph Theory
I'd definitely like to second that Rutgers recommendation. Great school for combinatorics and graph theory!

comment Simple homotopy type of 2-dimensional simplicial complexes
Well, the whitehead group depends only on the fundamental group, so all you need is a 2-complex whose fundamental group has non-trivial $\text{Wh}$. As you have noted, $\text{Wh}(\mathbb{Z}/5\mathbb{Z})$ is nontrivial. Note that you can get any group you want as the fundamental group of a 2-complex. (For what it is worth, I did not downvote).

comment What is $\infty^6$?
Given Mike's known proclivities, I expect that the correct answer to this question will involve a phrase isomorphic to "$\infty^6$ is the category of functors from the discrete category on six objects to..." :)

comment Contractibility of regular CW sphere minus open star
@TylerLawson Or you could use the minimal CW circle that glues the boundary of an interval to a single vertex. Then the open star of that vertex is everything and its complement is therefore empty.

comment How hard is it to destroy a diamond? (with a real)
I've upvoted in order to partially offset the inevitable backlash from environmentalists who react negatively to "blow up the continuum and destroy all the Suslin trees."

comment Generalize $\pi_0(B\mathcal{C})\cong\{\text{objects}\}/\{\text{morphisms}\}$ to categories internal to topological spaces
How exactly is the quotient (objects)/(morphisms) being defined? Do you mean to indicate that two objects $x$ and $y$ are equivalent if there exists $f:x \to y$? Or maybe $f:y \to x$? Or either?

comment Is the space of immersions of $S^n$ into $\mathbb R^{n+1}$ simply connected?
@QiaochuYuan If it helps, I suspect Ryan's comment lies in the space of unbased critiques from Professors to Grad Students.
