Persistence probability of random weyl polynomial
Résumé
In this paper, we obtain the persistence exponents of random Weyl polynomials in both cases: the nonnegative axis and the whole real axis. Our result confirms the predictions given by Schehr and Majumdar \cite{SM2}. In the nonnegative axis case, Dembo and Mukherjee \cite{DM} gave an upper bound for the persistence exponent by considering the persistence probability on a suitable interval. Our main contribution is to prove this upper bound is the exact exponent and to extend to the whole real axis case.
