Some remarks on the existence of a resolvent

Masanori Kishi (1975)

Noting that a resolvent is associated with a convolution kernel x satisfying the domination principle if and only if x has the dominated convergence property, we give some remarks on the existence of a resolvent.

On a class of convolution algebras of functions

Hans G. Feichtinger (1977)

Annales de l'institut Fourier

Similarity:

The Banach spaces Λ ( A , B , X , G ) defined in this paper consist essentially of those elements of L 1 ( G ) ( G being a locally compact group) which can in a certain sense be well approximated by functions with compact support. The main result of this paper is the fact that in many cases Λ ( A , B , X , G ) becomes a Banach convolution algebra. There exist many natural examples. Furthermore some theorems concerning inclusion results and the structure of these spaces are given. In particular we prove that simple conditions imply...
