SUMMARY

The discussion focuses on the proper notation for the Hom functor in mathematical typesetting, specifically the use of the longer dash in the expression \operatorname{Hom}(-,X). Users confirmed that using \operatorname{Hom}(-,X) in Overleaf produces the desired output without issues. The conversation clarifies that there are no problems with this notation, contrary to initial doubts expressed by one participant.

PREREQUISITES
  • Familiarity with LaTeX typesetting
  • Understanding of mathematical notation and functors
  • Basic knowledge of Overleaf as a LaTeX editor
  • Experience with operator names in LaTeX
NEXT STEPS
  • Explore advanced LaTeX typesetting techniques for mathematical expressions
  • Learn about the use of operators in LaTeX
  • Research best practices for typesetting functors in mathematics
  • Experiment with Overleaf features for enhanced mathematical notation
USEFUL FOR

Mathematicians, LaTeX users, and educators looking to improve their typesetting of mathematical expressions, particularly those involving functors and operator notation.

TL;DR
I want to know how to write the dash in Hom(--,B)
Hello!

Here's a piece of a print screen I did on Wikipedia's page on "Hom functor":

Does anybody knows how to do that dash that's longer than a mere minus sign?

Not a thing! I was certain that I had tried that in Overleaf and it didn't look good. But now I tried it and it looks fine.
