Abstract: We provide a study of Köthe sequence algebras. These are Fréchet sequence algebras which can be viewed as abstract analogoues of algebras of smooth or holomorphic functions. Of particular treatment are the following properties: unitality,… read more here.

Abstract: Abstract In this note we investigate contractibility properties in the class of the so-called DF-algebras. We also give a complete characterization of contractible Köthe co-echelon algebras. read more here.
