I assume you need this in the math editor.
I've used the following command to declare the math operator, it requires
the use of the amsmath package (or one of its associates)
\DeclareMathOperator*{\esssup}{ess\ sup}
This declares the ess sup operator, you can use:
\DeclareMathOperator*{\argmax}{argmax}
In order to declare the argmax operator, I don't remember if you need the
star or not, try both. Anyhow, it won't look too good in LyX, but on the
LaTeX output it should look fine when the formula is not inline.
