…
►As functions of $q$, ${a}_{n}\left(q\right)$ and ${b}_{n}\left(q\right)$ can be continued analytically in the complex $q$-plane.

##### 3: 1.10 Functions of a Complex Variable

…
►The function ${f}_{1}(z)$ on ${D}_{1}$ is said to be

*analytically continued along the path*$z(t)$, $a\le t\le b$, if there is a chain $({f}_{1},{D}_{1})$, $({f}_{2},{D}_{2}),\mathrm{\dots},({f}_{n},{D}_{n})$. … ►Then $f(z)$ can be continued analytically across $\mathit{AB}$ by*reflection*, that is, …##### 4: 2.5 Mellin Transform Methods

…
►Similarly, if $\mathcal{M}f\left(1-z\right)$ and $\mathcal{M}h\left(z\right)$ can be continued analytically to meromorphic functions in a right half-plane, and if the vertical line of integration can be translated to the right, then we obtain an asymptotic expansion for $I(x)$ for large values of $x$.
…
►Furthermore, $\mathcal{M}{f}_{1}\left(z\right)$ can be continued analytically to a meromorphic function on the entire $z$-plane, whose singularities are simple poles at $-{\alpha}_{s}$, $s=0,1,2,\mathrm{\dots}$, with principal part
…
►Similarly, if $\kappa =0$ in (2.5.18), then $\mathcal{M}{h}_{2}\left(z\right)$ can be continued analytically to a meromorphic function on the entire $z$-plane with simple poles at ${\beta}_{s}$, $s=0,1,2,\mathrm{\dots}$, with principal part
…Alternatively, if $\kappa \ne 0$ in (2.5.18), then $\mathcal{M}{h}_{2}\left(z\right)$ can be continued analytically to an entire function.
►Since $\mathcal{M}{h}_{1}\left(z\right)$ is analytic for $\mathrm{\Re}z>-c$ by Table 2.5.1, the analytically-continued
$\mathcal{M}{h}_{2}\left(z\right)$ allows us to extend the Mellin transform of $h$ via

##### 5: 18.2 General Orthogonal Polynomials

…
►It is assumed throughout this chapter that for each polynomial ${p}_{n}(x)$ that is orthogonal on an open interval $(a,b)$ the variable $x$ is confined to the closure of $(a,b)$

*unless indicated otherwise.*(However, under appropriate conditions almost all equations given in the chapter can be continued analytically to various complex values of the variables.) …##### 6: 19.7 Connection Formulas

…
►Provided the functions in these identities are correctly analytically continued in the complex $\beta $-plane, then the identities will also hold in the complex $\beta $-plane.

…
►The Coulomb functions given in this chapter are most commonly evaluated for real values of $\rho $, $r$, $\eta $, $\u03f5$ and nonnegative integer values of $\mathrm{\ell}$, but they may be continued analytically to complex arguments and order $\mathrm{\ell}$ as indicated in §33.13.
