Writing complexity classes in LaTeX

Question

Is there anyone who knows which package/style should I use to write a complexity class like this? You can see the highlighted word below, this is an all-caps word, but some letters are slightly bigger than the others. How to do this exactly in LaTeX?

Answer 1

Use small caps.

\documentclass{article}
\begin{document}
\textsc{LogSpace}
\end{document}
