The Spectral and the Maximal Spectral Space

2011
Generalizing the construction of the Stone space of a boolean algebra, the set of prime ideals of every MV-algebra A is endowed with the hull-kernel (also known as Zariski, or spectral) topology. The resulting space is denoted spec(A). In contrast to the Stone space of a boolean algebra, spec(A) is generally not rich enough to uniquely characterize A ...

Modules and Spectral Spaces

Communications in Algebra, 2012
We establish conditions for Spec(M) to be Noetherian and spectral space, w.r.t. different topologies. We used rings with Noetherian spectrum to produce plentiful examples of modules with Noetherian spectrum that have not appeared in the literature previously. In particular, we show that every ℤ-module has Noetherian spectrum.

Spectral Multipliers on Damek-Ricci Spaces

Journal of Lie Theory, 2007
Let \(S\) be a Damek-Ricci space. The first main result of the paper states that \(S,\) endowed with the right Haar measure \(\rho\) and the left invariant metric, is a Calderón-Zygmund space. The second result is a Hörmander type theorem for spectral multipliers associated to the Laplacian \(\Delta.\) Let \(\psi\in C_c^\infty(\mathbb{R}^+)\) be ...

Scale-Space Spectral Representation of Shape

2010 20th International Conference on Pattern Recognition, 2010
We construct a scale space of shape of closed Riemannian manifolds, equipped with metrics derived from spectral representations and the Hausdorff distance. The representation depends only on the intrinsic geometry of the manifolds, making it robust to pose and articulation. The computation of shape distance involves an optimization problem over the 2^p-

Locales as spectral spaces

Algebra universalis, 2013
Stone's representation theorem for distributive lattices yields a dual equivalence between the category \(\mathsf{DLat}\) of (bounded) distributive lattices and that of spectral spaces, \(\mathsf{Spec}\). Several results characterizing subcategories of \(\mathsf{DLat}\) in terms of properties of their corresponding spectral spaces have appeared in the ...

Space, Spectrality, and Parability

2012
In the epigraph above, Henri Lefebvre points to the necessity of analyzing space by bringing back the subject and object into the abject that constitutes social space. It seems, from a philosophical perspective, both necessary and impossible because the space of modernity, the space of the modern city and the crowd, produced a concomitant anxiety ...

Spectral Mapping Theorems and Spectral Space-Independence

2003
Motivated by the interest in spectral mapping theorems for C o-semigroups of bounded linear operators on a Banach space (see, e.g., [8]), we present here a unified approach for spectral mapping theorems for various kinds of functional calculi. As a byproduct of our investigation, and motivated by [7], we obtain that the spectrum of an operator, when ...
