Bell numbers in Matsunaga's and Arima's Genjikō combinatorics: Modern perspectives and local limit theorems
Xiaoling Dou, Hsien-Kuei Hwang, Chong-Yi Li
We examine and clarify in detail the contributions of Yoshisuke Matsunaga (1694?--1744) to the computation of Bell numbers in the eighteenth century (in the Edo period), providing…
Universal Axion Backreaction in Flux Compactifications
Thomas W. Grimm, Chongchuo Li
We study the backreaction effect of a large axion field excursion on the saxion partner residing in the same multiplet. Such configurations are relevant in attempts…
Asymptotic Flux Compactifications and the Swampland
Thomas W. Grimm, Chongchuo Li, Irene Valenzuela
We initiate the systematic study of flux scalar potentials and their vacua by using asymptotic Hodge theory. To begin with, we consider F-theory compactifications on Calabi-Yau fou…
Infinite Distance Networks in Field Space and Charge Orbits
Thomas W. Grimm, Chongchuo Li, Eran Palti
The Swampland Distance Conjecture proposes that approaching infinite distances in field space an infinite tower of states becomes exponentially light. We study this conjecture for…
