5)]. The more detailed results of O. HAUPT  and J. E. WILKINS , A. WINTNER  on the subject cannot be discussed here. S. qi(t)!

GHIZZETTI , 1. M. SOBOL . For a further investigation on the subject see A. 'VINTNER . 8, Linear asymptotic equilibrium. We shall first state and prove the following statement whose interest goes beyond the application we will give below.
