(3) Misplaced alignment tab character &.

You have placed an alignment tab character '&' in the wrong place. If you want to align something, you must write it inside an align environment such as \begin{align} … \end{align}, \begin{tabular} … \end{tabular}, etc. If you want to write an ampersand '&' in text, you must write \& instead.

I can't figure out why you would want to use a tab mark
here. If you just want an ampersand, the remedy is
simple: Just type `I\&' now. But if some right brace
up above has ended a previous alignment prematurely,
you're probably due for more error messages, and you
might try typing `S' now just to see what is salvageable.

Gracias por cualquier ayuda para eliminar dichos errores. Especialmente, sería genial ayudarme a construir mis listas de paquetes de uso y otras para obtener un resultado sin errores al dorso. Gracias

Answer 1

1. El error inicial es una incompatibilidad entre babel/ polishy el amssymbpaquete, como puedes observar con este mínimo ejemplo:

   \documentclass{article}
   \usepackage[polish]{babel}
   \usepackage{amssymb}
   \begin{document}
   \end{document}
   

   Agregue las siguientes líneas después de cargar el babelpaquete.

   \usepackage[dutch,polish,swedish,french,german,russian,main=english]{babel}
   \let\plll\lll
   \let\lll\relax
   

2. Con respecto al segundo error \eqnumcolorindefinido, reemplácelo \renewcommandpor \newcommand(línea 36 del código que publicó)

3. En la bibliografía, en la cadena Chaos, Solitons & Fractals, sustituir &por \&.

4. Al parecer estás escribiendo matemáticas. En este caso, utilice el modo matemático y los comandos proporcionados para los símbolos matemáticos. En lugar de ℓ∞, tal vez quisiste escribir $\ell_\infty$(polaco l subíndice infinito) o $\ell^\infty$(polaco l superíndice infinito). Si el símbolo l fue la única razón para incluirlo polishentre las opciones del babelpaquete, elimínelo y no necesitará la primera solución anterior.

5. En el nombre Maciej Sļeczka, no uses la letra lseguida del Unicode para una cedille, sino la letra ļque ya incluye la cedille (por ejemplo, cópiala de esta publicación si no sabes escribirla).
