comment Need a good name for an algorithmic problem in groups that generalizes the conjugacy problem
I think after all that this terminology is quite precise and easy to generalize. One cannot expect to find a short unique descriptive name for every algorithmic problem. Besides, i was interested not only in solvability, but in solutions too.

comment Need a good name for an algorithmic problem in groups that generalizes the conjugacy problem
Thanks Nick :). This might work for me. I have already thought of equations, but there can be slight variations of the problem where one would be looking not for the conjugating elements themselves but only for the conjugates of $g_1,\dotsc,g_n$. Also one may be interested in the decision problem: whether or not a solution exists.

suggest "generalized conjugacy problem"

Well, but how to call this particular kind of factorization?

comment Can closed compacts in a topological group behave “paradoxically” with respect to unions, intersections, and one-sided translations?
Well, this does not answer my question.

comment When are configuration spaces aspherical?
Would you mind giving a reference for Fox-Neuwirth theorem, please? I can't find it with Google.

comment “Natural” pairings between exterior powers of a vector space and its dual
If i understand [differential forms and integrals] well, to integrate a differential form with the first pairing, one needs to cut the space into rectangles/parallelepipeds, and with the second pairing, one needs to cut the space into triangles/tetrahedra. :)

comment Why do we teach calculus students the derivative as a limit?
"What benefit is there in introducing to calculus students the $h→0$ definition of a derivative?" -- you have to define it anyway, don't you? I agree that calculating a derivative of something like $x\mapsto 3x^2$ by definition can be boring, it is better to ask a student to derive the product or the quotient rule for the derivative, for example.
