Ville T. Turunen, Gennadi Vainikko · Zeitschrift für Analysis und ihre Anwendungen · 1998
This paper deals with periodic pseudodifferential operators on the unit circle \mathbb T^1 = \mathbb R^1/ \mathbb Z^1 . The main results are asymptotic expansions for adjoints and products of periodic pseudodifferential operators.
