What's the mistake here?

Post by knapitur »

Hello people. I get this feedback from Winedt when I try to compile my code:
* Local config file bblopts.cfg used
*
("C:\Archivos de programa\MiKTeX 2.9\tex\latex\00miktex\bblopts.cfg")
("C:\Archivos de programa\MiKTeX 2.9\tex\generic\babel\spanish.ldf"
("C:\Archivos de programa\MiKTeX 2.9\tex\generic\babel\babel.def")))
("C:\Documents and Settings\JUAN\Mis documentos\Latex\prueba.aux")
("C:\Archivos de programa\MiKTeX 2.9\tex\latex\amsfonts\umsa.fd")
("C:\Archivos de programa\MiKTeX 2.9\tex\latex\amsfonts\umsb.fd")
! Extra }, or forgotten $.
<recently read> }

l.45 ...A \in M_{n}(R): det(A) \neq 0 \}$ y $\dot$
la multiplicaci\'on usual...

?

Process has been terminated ...
and the mentioned line is this one:
Sea $GL_{n}(R)=\{A \in M_{n}(R): det(A) \neq 0 \}$ y $\dot$ la multiplicaci\'on usual de matrices en $M_{n}(R)$. Entonces $(GL_{n}(R), \dot)$ es un grupo. Este grupo es importante en matem\'aticas y se conoce con el nombre de \emph{Grupo General Lineal}.
I don't see any mistake, I don't have any idea on what could be wrong! Please help me understand.

Hi,

welcome to the board!

\dot requires an argument and places a dot accent above it, such as \dot{x}. \dot{} would work, however consider using \cdot without argument.
