My main activity is in number theory of integral positive ternary quadratic forms. This began through years of working with Irving Kaplansky. Much of his unpublished writing on quadratic forms can be found as pdfs at http://zakuski.math.utsa.edu/~kap/forms.html and about Lie and Jordan superalgebras at http://zakuski.math.utsa.edu/~kap/superalgebra.html One of my own email addresses can be found easily using the search feature at http://www.ams.org/cml and just putting in my last name

comment Error term for prime harmonic
Could be. Having more than one author seems right, also the title is promising. Let me try a few pages online...

there is also some two or three volume thing which is entirely identities and estimates in number theory. I borrowed one volume once but cannot remember author(s). Just a list of results with individual references.

Bach and Shallit include a list of many useful estimates, title is probably Algorithmic Number Theory.

comment Reference request: minimal (maximal) Lorentzian surfaces in $\mathbb{R}^{1,2}$
@Piojo, quite possible. Meanwhile, I am having trouble finding a web page for the Granada Department of Geometry and Topology, which is clearly separate from the Department of Applied Mathematics that I found.

The names that come to mind are Lopez and Ros; it has been a while. ugr.es/~aros

comment Are there any serious investigations of whether “mathematicians do their best work when they're young”?
Elizabeth, not for me. I've often gotten overruled, of course. The worst one was some guy who asked about the philosophy behind Mochizuki's work, which is still unconfirmed, years later.

@YemonChoi Meanwhile, I voted to close. Not fond of fishing expeditions.
