## Abstract We consider two categories with one object, namely the set of all partial functions of one variable from the set of natural numbers into itself; the morphisms are the partial recursive operators in one case, and certain continuous partial mappings in the other case. We show that these c
## Abstract Spectral properties of the semiβelliptic operator equation image in __L__~__p__~ (1 < p < β) spaces are investigated. In particular it is proved that there exists __ΞΌ0__ such that if ΞΌ__> ΞΌ0__, then __A__~ΞΌ, __P__~ has the point spectrum and Ξ»~k~(__A__~ΞΌ, __P__~) Λ where __A__~ΞΌ, __P_
