31: 26.10 Integer Partitions: Other Restrictions

… ► $p_m(𝒟,n)$ denotes the number of partitions of $n$ into at most $m$ distinct parts. …The set $\{n\ge 1|n\equiv \pm j(modk)\}$ is denoted by $A_{j,k}$. … ►It is known that for $k>3$, $p(𝒟k,n)\ge p(\in A_{1,k+3},n)$, with strict inequality for $n$ sufficiently large, provided that $k=2^m-1,m=3,4,5$, or $k\ge 32$; see Yee (2004). … ►where $I_1\left(x\right)$ is the modified Bessel function (§10.25(ii)), and …The quantity $A_k(n)$ is real-valued. …

32: 28.8 Asymptotic Expansions for Large $q$

… ►Also let $\xi =2\sqrt{h}\cos x$ and $D_m\left(\xi \right)={\mathrm{e}}^{-{\xi }^2/4}{\mathrm{𝐻𝑒}}_m\left(\xi \right)$ (§18.3). … ►

${\sigma }_m\sim 1+{\displaystyle \frac{s}{2^{3}h}}+{\displaystyle \frac{4s^2+3}{2^7{h}^2}}+{\displaystyle \frac{19s^3+59s}{2^{11}{h}^3}}+\mathrm{\cdots },$

… ►The approximations are expressed in terms of Whittaker functions $W_{\kappa ,\mu }\left(z\right)$ and $M_{\kappa ,\mu }\left(z\right)$ with $\mu =\frac{1}{4}$; compare §2.8(vi). … ►Subsequently the asymptotic solutions involving either elementary or Whittaker functions are identified in terms of the Floquet solutions ${\mathrm{me}}_{\nu }(z,q)$ (§28.12(ii)) and modified Mathieu functions ${\mathrm{M}}_{\nu }^{(j)}(z,h)$ (§28.20(iii)). …

33: 3.9 Acceleration of Convergence

… ►A transformation of a convergent sequence $\{s_n\}$ with limit $\sigma$ into a sequence $\{t_n\}$ is called limit-preserving if $\{t_n\}$ converges to the same limit $\sigma$. … ►This transformation is accelerating if $\{s_n\}$ is a linearly convergent sequence, i. … ►Then the transformation of the sequence $\{s_n\}$ into a sequence $\{t_{n,2k}\}$ is given by … ►Then $t_{n,2k}={\epsilon }_{2k}^{(n)}$. … ►We give a special form of Levin’s transformation in which the sequence $s=\{s_n\}$ of partial sums $s_n={\sum }_{j=0}^n{a}_j$ is transformed into: …
