物理复苏外推

Physical Resurgent Extrapolation

Ovidiu Costin, Gerald V. Dunne

摘要:

物理函数的展开由它们的奇点控制,奇点具有特殊的结构,因为它们本身是物理的,对应于瞬子、焦散线或鞍形。复苏渐近在数学上形式化了这一想法,并导致更强大的外推方法从有限数量的扩展项中提取物理信息,包括精确解码非微扰效应。

英文摘要:

Expansions of physical functions are controlled by their singularities, which have special structure because they themselves are physical, corresponding to instantons, caustics or saddle configurations. Resurgent asymptotics formalizes this idea mathematically, and leads to significantly more powerful extrapolation methods to extract physical information from a finite number of terms of an expansion, including precise decoding of non-perturbative effects.
