Combining Igusa's conjectures on exponential sums and monodromy with semi-continuity of the minimal exponent
Raf Cluckers, Kien Huu Nguyen
We combine two of Igusa's conjectures with recent semi-continuity results by Mustaţă and Popa to form a new, natural conjecture about bounds for exponential sums. These bounds have…
