广义幂级数的多和性

Multisummability for generalized power series

Jean-Philippe Rolin, Tamara Servi, Patrick Speissegger

摘要:

我们开发的多和性,在正实方向上,广义幂级数与自然支持,我们证明了o-极小的实域的扩展,这些系列的所有多和。由此产生的结构扩展了$\mathbb{R}_{\mathcal{G}}$和所有收敛的广义幂级数与自然支持生成的$\mathbb{R}_{\mathrm{an}^*}$的约简;特别是,它的指数函数扩展定义了$(0,\infty)$上的Γ函数和$(1,\infty)$上的Zeta函数。

英文摘要:

We develop multisummability, in the positive real direction, for generalized power series with natural support, and we prove o-minimality of the expansion of the real field by all multisums of these series. This resulting structure expands both $\mathbb{R}_{\mathcal{G}}$ and the reduct of $\mathbb{R}_{\mathrm{an}^*}$ generated by all convergent generalized power series with natural support; in particular, its expansion by the exponential function defines both the Gamma function on $(0,\infty)$ and the Zeta function on $(1,\infty)$.
