►This singularity is

*removable*if ${a}_{n}=0$ for all $$, and in this case the Laurent series becomes the Taylor series. …Lastly, if ${a}_{n}\ne 0$ for infinitely many negative $n$, then ${z}_{0}$ is an*isolated essential singularity*. … ►An isolated singularity ${z}_{0}$ is always removable when ${lim}_{z\to {z}_{0}}f(z)$ exists, for example $(\mathrm{sin}z)/z$ at $z=0$. … ►A*cut domain*is one from which the points on finitely many nonintersecting simple contours (§1.9(iii)) have been removed. … ►Branches of $F(z)$ can be defined, for example, in the cut plane $D$ obtained from $\u2102$ by removing the real axis from $1$ to $\mathrm{\infty}$ and from $-1$ to $-\mathrm{\infty}$; see Figure 1.10.1. …##### 4: 25.14 Lerch’s Transcendent
