Abstract: We provide complete structural theorems for the so-called quasiasymptotic behavior of non-quasianalytic ultradistributions. As an application of these results, we obtain descriptions of quasiasymptotic properties of regularizations at the origin of ultradistributions and discuss connections with Gelfand–Shilov type spaces.

Keywords: Quasiasymptotic behavior, ultradistributions, regularly varying functions
