Quiero una ecuación de varias líneas (preferiblemente incluso centrada con la columna apropiada, ya que las ecuaciones de una sola línea que ya tengo usando [y] o $$ $$ no están centradas) en parte de la descripción de \newglossaryentry.
Básicamente quiero, centradas en la columna del glosario, ecuaciones de una sola línea y de varias líneas.
¡Gracias!
PD: pensé que podría sacar algo de esto:ingrese la descripción del enlace aquí pero no pude...

It is said that $f$ is holomorphically extended over $U$ if such a $g$ exists. A simple example is the function $$f(z) = \frac{\sin(z)}{z}$$ at $z=0$ (even this: \[f(z) = \frac{\sin(z)}{z}\] doesn't center.).

Envolver el contenido en un minipageentorno permite que las matemáticas mostradas se centren en el longtableentorno. Pero hacer eso cada vez sería tedioso, inflexible y propenso a errores.
Una mejor opción es usar el \newcolumntypecomando del arraypaquete para configurar un nuevo tipo de columna para entornos tabulares que luego podemos usar para definir un nuevo estilo de glosario my3col. Este estilo se basará en long3colel tipo de columna de la descripción, pero con un cambio.
Lo cargué glossariesanteriormente para que \glsdescwidthesté disponible cuando se defina el nuevo tipo de columna. Esto a su vez se define antes de configurar el nuevo estilo de glosario que hará uso del mismo. Finalmente, se activa el nuevo estilo.
