$$\Lambda_0$$-nuclear operators and $$\Lambda_0$$-nuclear spaces in $$p$$-adic analysis. (English) Zbl 0948.46052
Summary: For a Köthe sequence space, the classes of $$\Lambda_0$$-nuclear spaces and spaces with the $$\Lambda_0$$-property are introduced and studied and the relation between them is investigated. Also, we show that, for $$\Lambda_0\neq c_0$$, these classes of spaces are in general different from the corresponding ones for $$\Lambda_0= c_0$$, which have been extensively studied in the non-Archimedean literature.
