Math & Science ⇒ autoref and theorems

[obco]

The autoref command can't tell the difference between theorems and lemmas on the same counter. How do I get round this problem?

(1) Using the thm-autoref package, which is part of the thmtools package, still gives me a bunch of errors.

Code: Select all

\documentclass{article}

\usepackage{amsmath, amsthm}
\usepackage{thm-autoref}

\newtheorem{theorem}{Theorem}
\newtheorem{lemma}[theorem]{Lemma}

\usepackage{hyperref}

\begin{document}

\begin{theorem}[My Theorem]\label{thm:mytheorem}
This is my theorem.
\end{theorem}

\begin{lemma}[My Lemma]\label{thm:mylemma}
This is my lemma.
\end{lemma}

My Theorem is autoreferenced by \autoref{thm:mytheorem}, and My Lemma by \autoref{thm:mylemma}.

\end{document}

(2) Using the cleveref package, the lemma is still referred to as a theorem.

Code: Select all

\documentclass{article}

\usepackage{amsmath, amsthm}

\newtheorem{theorem}{Theorem}
\newtheorem{lemma}[theorem]{Lemma}

\usepackage{hyperref}
\usepackage{cleveref}

\begin{document}

\begin{theorem}[My Theorem]\label{thm:mytheorem}
This is my theorem.
\end{theorem}

\begin{lemma}[My Lemma]\label{thm:mylemma}
This is my lemma.
\end{lemma}

My Theorem is autoreferenced by \cref{thm:mytheorem}, and My Lemma by \cref{thm:mylemma}.

\end{document}

Any help would be much appreciated.

Cheers.

Hi,

you could use the \crefname command provided by the cleveref package and the optional argument of the \label command, to get the desired result. Have a look at the following example:

Code: Select all

\documentclass{article}
\usepackage{cleveref}
\newtheorem{theorem}{Theorem}
\newtheorem{lemma}[theorem]{Lemma}
\crefname{lemma}{lemma}{lemmas}

\begin{document}

\begin{theorem}[My Theorem]\label{thm:mytheorem}
  This is my theorem.
\end{theorem}

\begin{lemma}[My Lemma]\label[lemma]{thm:mylemma}
  This is my lemma.
\end{lemma}

My Theorem is autoreferenced by \cref{thm:mytheorem}, and My Lemma by \cref{thm:mylemma}.

\end{document}

Lol, so simple! thnx
