Laurent series of exp 1/z
WebThe geometric series in this equation has ratio z=w. Therefore, the series converges, i.e. the formula is valid, whenever jz=wj<1, or equivalently when jzj Web27 feb. 2024 · f(z) = 1 z(z − 1) has isolated singularities at z = 0 and z = 1. Show that both are simple poles. Solution In a neighborhood of z = 0 we can write f(z) = g(z) z, where g(z) = 1 z − 1. Since g(z) is analytic at 0, z = 0 is a finite pole. Since g(0) ≠ 0, the pole has order 1, i.e. it is simple. Likewise, in a neighborhood of z = 1,
