I'm a mathematician working in algebra. I've been using TeX since 1987, but couldn't write my Ph.D. thesis with it. Sob!

I teach LaTeX at my university, besides the mathematics courses. I'm the author of some LaTeX packages and even of one Plain TeX package. At my site it's possible to download my book on LaTeX programming (in Italian, sorry).

Here's my motto for TeX.SX:

Pronto prontissimo son come il fulmine: sono il factotum della città. (From "Il barbiere di Siviglia", music by Gioachino Rossini, libretto by Cesare Sterbini.)

Perhaps it's better if you tell exactly what you have in mind: I think that \hspace is not what you need. Probably there are better ways.

comment How do I get filled black < and \leq?
@user24406 If you use a package such as fourier or newtxmath for different fonts, the shape of \blacktriangleleft will not fit any more with the shape of <. But in that case you'll probably would not use the filled triangle together with <, just because they would be too different.

comment Korean characters in article title
Are you sure you need utf8x? I believe it's simply better to use utf8 (this avoids the disputable opt@inputenc.sty trick).

comment How do I get filled black < and \leq?
@user24406 This works for the standard Computer Modern fonts; if you use a different math font, this might need a different workaround.

comment How to write geometric arcs notation without arcs package?
The arcs package has very serious bugs. See tex.stackexchange.com/questions/86036/… and tex.stackexchange.com/questions/15468/…

comment Define new command which insert environment
Welcome to TeX.SX! Unfortunately it's not possible. For one liners, as you seem to want, listings provides \lstinline.

comment stix font error: PK font stix-mathrm could not be created
You might have updated stix.sty without having done so with the fonts. MiKTeX is particularly known for not updating font maps.

comment Why is “Lemma 9.6” the default and not “9.6 Lemma”?
It mostly depends on what you are thinking to be numbering: if you're numbering paragraphs (à la française), then the number goes first; if you're numbering the statements, then the number goes second.

comment How to use line styles in gnuplot?
While gnuplot output can be used in (La)TeX, I believe that this is not on topic for the site.
