why NO multiple Laurent series ??
why are ther Taylor series in several variables [tex] (x_{1} , x_{2} ,..., x_{n} [/tex] but there are NO Laurent series in several variables ? why nobody has defined this series , or why they do not appear anywhere ?
i think there are PADE APPROXIMANTS in serveral variables but i have never NEVER heard of multiple Laurent series.
