@FedericoPoloni Wow, this is great! I emailed TandfF about this and let's see if they are as dedicated as MathSciNet…

comment How to cite authors from any country correctly?
For Stanley J. Osher your MathSciNet and Google do not agree for me (let alone that googling is itself subjective): MathSciNet suggests "Stanley J. Osher" while "S. Osher" produces most Google hits for me ("Stanley Osher" is second place and "S. J. Osher" is third place). Another nice try is "Jeffrey C. Lagarias"…

Thing is that "best known" is subjective… Or do you mean "best known to yourself"? An example from outside academia: Is is T.C. Boyle, T. Coraghessan Boyle or Tom Coraghessan Boyle?

As a frequent user of academia.sx I am not aware of different cultures regarding names in different fields of science (as long as the order in not concerned!), hence my vote to migrate.

I'm voting to close this question as off-topic because it belongs to academia.stackexchange.com.

I think only the last sentence gives the correct approach (unless you are D. Knuth).

comment On convergence of convex bodies
Wlog you can assume that $K$ lies in the upper half plane. Isn't it clear that $\partial K\cap \epsilon S^{n-1}$ is the graph of a convex function for $\epsilon$ small enough, and doesn't this imply that you can contract along radial lines?

comment Projecting on a a special polyhedron
As far as I remember, projecting onto polyhedra is in general a hard problem (probably as hard as a generic second order cone program?). That your polyhedron is symmetric about the origin is in fact its only special property, i.e. all symmetric polyhedra are of this form.

Wouldn't then $V$ be contained in $F$?

comment Convex Optimization in an Ellipsoid
Why should it? Since $A$ is PSD this is a convex quadratic program. By the way: Isn't there a closed form solution (using $A^{-1}$)?

comment Are there any non-linear solutions of Cauchy's equation ($f(x+y)=f(x)+f(y)$) without assuming the Axiom of Choice?
As of today the link to the short proof of "addive + measurable implies liner" is broken.

@AndréHenriques I thought the same and just wanted to hear the OPs and other opinions.

comment When is an erratum necessary?
Should this be moved to academia.stackexchange.com or is it to be expected that answers will be specific for mathematics?
