Local Spectral Properties of Typical Contractions on ℓp-Spaces
We study some local spectral properties of contraction operators on ℓ p , 1 < p < ∞ from a Baire category point of view, with respect to the Strong*...

A Noncommutative Bishop Peak Interpolation-Set Theorem
We prove a noncommutative version of Bishop’s peak interpolation-set theorem. -
Decomposability and local spectral properties of a normal linear relation
Our objective in this paper is to show that, similarly to the case of normal operators, a normal linear relation on a Hilbert space H satisfies...

THE FREENESS PROPERTY FOR LOCALLY NILPOTENT DERIVATIONS OF R[2]
Let R be a principal ideal domain containing ℚ and let ξ be a nonzero locally nilpotent derivation of the polynomial ring A = R [2] . We prove in this...

Constructive Semigroups with Apartness: A State of the Art
This chapter aims to provide a clear and understandable picture of constructive semigroups with apartness in Bishop’s style of constructive... -

A Constructive Picture of Noetherian Conditions and Well Quasi-orders
From a constructive perspective the many notions of Noetherianity and well quasi-order form a rich landscape, which we here explore. Besides the... -
Sufficient Conditions for Extended Spectral Decomposable Multi-Valued linear operators
In this paper, we develop the notion of spectral decomposability of a multi-valued linear operator (linear relation) in Banach spaces using subsets...

Algebras of Complemented Subsets
Complemented subsets were introduced by Bishop, in order to avoid complementation in terms of negation. In his two approaches to measure theory...
