DeclareMathOperator not working on some math names with a number at the end

I am trying to use DeclareMathOperator to make names for some Maple generated latex which uses the special function LommelS1



For some reason I can't figure out, it is not working.



documentclass[11pt]{article}
usepackage{amsmath,mathtools,amssymb}
DeclareMathOperator{LommelS1}{LommelS1}
DeclareMathOperator{LommelS2}{LommelS2}

begin{document}
[
LommelS1 x
]
end{document}


Error is



>lualatex foo.tex
This is LuaTeX, Version 1.07.0 (TeX Live 2018)
restricted system commands enabled.
(/usr/local/texlive/2018/texmf-dist/tex/latex/latexconfig/epstopdf-sys.cfg)))
(/usr/local/texlive/2018/texmf-dist/tex/latex/amsfonts/umsa.fd)
(/usr/local/texlive/2018/texmf-dist/tex/latex/amsfonts/umsb.fd)
! Use of LommelS doesn't match its definition.
l.14 LommelS1
x
?


Notice it is looking for LommelS but the operator is LommelS1



It seems the number at the end of the operator is confusing it. Also when I remove the second DeclareMathOperator now it works:



documentclass[11pt]{article}
usepackage{amsmath,mathtools,amssymb}
DeclareMathOperator{LommelS1}{LommelS1}
%DeclareMathOperator{LommelS2}{LommelS2} %when commented, it works
begin{document}
[
LommelS1 x
]
end{document}


But I need to use LommelS1 and LommelS2 so the numbers at the end are important since Maple latex will contain both such names.



Is where a way around this?

    Command names cannot have digits in them, only letters.

  • newcommand{LommelS}[1]{operatorname{LommelS#1}} will do if LommelS is always followed by 1 or 2 (or a single digit). A slower routine is needed otherwise. Without more information it's not possible to say more.

  • @egreg thanks. Yes, the commands from Maple only have 1 or 2 at the end. So I will try your suggestion above now.

If there's no LommelS without a following digit and Maple always generates either LommelS1 or LommelS2, then it's easy:



newcommand{LommelS}[1]{operatorname{LommelS#1}}


You should know that only letters are accepted in command names that have a letter in their name (only a single nonletter can form a command name).
