Irreducible representations of nilpotent groups generate classifiable C*-algebras
, 2016 We show that C*-algebras generated by irreducible representations of finitely generated nilpotent groups satisfy the universal coefficient theorem of Rosenberg and Schochet.

Journal of the Association for Information Science and Technology, EarlyView.Abstract ChatGPT and related technologies have revived an old issue in information science (IS) concerning information retrieval (IR) versus document retrieval. Since 1950, the term IR has primarily been used as a misnomer for document retrieval. This problematic terminology reflects a desire to go beyond documents and provide, in response to user ...

Nuclearity and ${\mathrm {CPC}^*}$ -Systems
Forum of Mathematics, SigmaWe write arbitrary separable nuclear $\mathrm {C}^*$ -algebras as limits of inductive systems of finite-dimensional $\mathrm {C}^*$ -algebras with completely positive connecting maps. The characteristic feature of such ${\mathrm {CPC}^*}$

Separable subalgebras of a class of Azumaya algebras
International Journal of Mathematics and Mathematical Sciences, 1998 Let S be a ring with 1, C the center of S, G a finite automorphism group of S of order n invertible in S, and SG the subnng of elements of S fixed under each element in G. It is shown that the skew group ring S*G is a G′-Galois extension of (S*G)G′ that

Separately continuous algebras
Theoretical Computer Science, 1983 An ordered algebra is separately \(\Delta\)-continuous if it has directed joins, and the operations preserve these joins in each variable separately. For infinitary signatures, free separately \(\Delta\)- continuous algebras are proved not to exist, in contrast with the jointly continuous algebras [see \textit{E. Nelson}, Lect. Notes Math. 871, 315-334

Asymptotic properties of cross‐classified sampling designs
Canadian Journal of Statistics, EarlyView.Abstract We investigate the family of cross‐classified sampling designs across an arbitrary number of dimensions. We introduce a variance decomposition that enables the derivation of general asymptotic properties for these designs and the development of straightforward and asymptotically unbiased variance estimators.

Archimedean Atomic Lattice Effect Algebras with Complete Lattice of Sharp Elements
Symmetry, Integrability and Geometry: Methods and Applications, 2010 We study Archimedean atomic lattice effect algebras whose set of sharp elements is a complete lattice. We show properties of centers, compatibility centers and central atoms of such lattice effect algebras.

Compact Hermitian operators on projective tensor products of Banach algebras
International Journal of Mathematics and Mathematical Sciences, 2002 Let U and V be, respectively, an infinite- and a finite-dimensional complex Banach algebras, and let U⊗pV be their projective tensor product. We prove that (i) every compact Hermitian operator T1 on U gives rise to a compact Hermitian operator T on U⊗pV

Earthquake Engineering &Structural Dynamics, EarlyView.ABSTRACT Multivariate ground motion models (GMMs) that capture the correlation between different intensity measures (IMs) are essential for seismic risk assessment. Conventional GMMs are often developed using a two‐stage approach, where separate univariate models with predefined functional forms are fitted first, and correlation is addressed in a ...
