Integrability of oscillatory functions on local fields: Transfer principles
Integrability of oscillatory functions on local fields: Transfer principles
For oscillatory functions on local fields coming from motivic exponential functions, we show that integrability over $Q_p^n$ implies integrability over $F_p ((t))^n$ for large $p$, and vice versa. More generally, the integrability only depends on the isomorphism class of the residue field of the local field, once the characteristic of …
