Clasificar las singularidades en C de:




Bueno. No sé, lo subo porque sino se suben más cosas en offtopic que ejercicios, porque estoy de mal humor y porque tengo una pregunta fundamental y calculo que súper burra, pero no sé, ya no me acuerdo nada de Laurent (razón por la cual usualmente entra para el primer parcial, i think):

Si yo tengo la función expresada como la suma de dos funciones, y tengo un punto que es singularidad de una de las partes.. enotnces, digamos, es singularidad de la función, o no? y no alcanza con clasificarlo para ese término? si en el otro término da un numerito...

bueno, no sé, no me peguen (no me pegues pablo, digamos. o al menos no recuerdes estas burradas cuando corrijas mi parcial)

en caso de no estar absolutamente equivocada, lo que yo haría es más o menos esto:

Hola! Ese ejercicio justo lo estábamos viendo ayer con la gente, y me parece que esta bien analizar por términos separados, igual de última, fijate que podes unir todo en una expresión, sacando común denominador (se llamaba asi?) y esta todo más que bien. Porque siguen valiendo las cosas que dijiste. Fijate que si lo unis, cuando quieras encontrar el polo, siempre vas a encontrar una función G(z) tal que G(zo) sea distinta de 0 y esta todo más que piola.
Igual estaría bueno que alguien que la tenga más clara, aclare las cuestiones! jaja


saludos!

uh me olvide! sí, las singularidades de la segunda parte son polos simples, porque si vos tomas el limite de F(z)(z-zo)¨m ves que basta con que m sea igual a 1 para que el limite te de un número distinto de cero y todo más que piola!
(perdón por no usar Latex, pero como diría P.de Napo "el tiempo es tirano!")
