Integration of oscillatory and subanalytic functions

Abstract: We prove the stability under integration and under Fourier transform of a concrete class of functions containing all globally subanalytic functions and their complex exponentials. This paper extends the investigation started in [26] and [8] to an enriched framework including oscillatory functions. It provides a new example of fruitful interaction between analysis and singularity theory.

“…In particular, they handle the case x → f (x, y) log(g(x, y)) dy for globally subanalytic f (x, y) and g(x, y). More recently, Cluckers et al [1] have considered oscillatory integrals x → f (x, y)e ig(x,y) for globally subanalytic f (x, y) and g(x, y). These are motivated by Fourier transformation and lead necessarily out of the o-minimal context.…”
