The Geometric Arveson-Douglas Conjecture through Veronese Embeddings

Francesca Arici, Yufan Ge, Dimitris Michail Gerontogiannis

We prove invariance of the geometric Arveson-Douglas conjecture under Veronese embeddings of projective varieties. This provides new examples of singular varieties satisfying the c…

Quadratic subproduct systems, free products, and their C*-algebras

Francesca Arici, Yufan Ge

Motivated by the interplay between quadratic algebras, noncommutative geometry, and operator theory, we introduce the notion of quadratic subproduct systems of Hilbert spaces. Spec…

KK-duality for the Cuntz-Pimsner algebras of Temperley-Lieb subproduct systems

Francesca Arici, Dimitris Michail Gerontogiannis, Sergey Neshveyev

We prove that the Cuntz-Pimsner algebra of every Temperley-Lieb subproduct system is KK-self-dual. We show also that every such Cuntz-Pimsner algebra has a canonical KMS-state, whi…

Decomposable Blaschke products of degree

Asuman Güven Aksoy, Francesca Arici, M. Eugenia Celorrio +1

We study the decomposability of a finite Blaschke product of degree into degree- Blaschke products, examining the connections between Blaschke products, the ellipt…

Split extensions and KK-equivalences for quantum projective spaces

Francesca Arici, Sophie Emma Zegers

We study the noncommutative topology of the -algebras of the quantum projective spaces within the framework of Kasparov's bivariant K-theory. In particu…

Gysin sequences and SU(2)-symmetries of C*-algebras

Francesca Arici, Jens Kaad

Motivated by the study of symmetries of C*-algebras, as well as by multivariate operator theory, we introduce the notion of an SU(2)-equivariant subproduct system of Hilbert spaces…

Veronese and Segre morphisms between non-commutative projective spaces

Francesca Arici, Francesco Galuppi, Tatiana Gateva-Ivanova

We study Veronese and Segre morphisms between non-commutative projective spaces. We compute finite reduced Gröbner bases for their kernels, and we compare them with their analogues…

Toeplitz extensions in noncommutative topology and mathematical physics

Francesca Arici, Bram Mesland

We review the theory of Toeplitz extensions and their role in operator K-theory, including Kasparov's bivariant K-theory. We then discuss the recent applications of Toeplitz algebr…

Pure infiniteness and paradoxicality for graph -algebras

Francesca Arici, Baukje Debets, Karen R. Strung

We obtain necessary and sufficient conditions for pure infiniteness of the path groupoid -algebra of a row-finite graph without sinks. In particular we show that for such a pa…

Associated noncommutative vector bundles over the Vaksman-Soibelman quantum complex projective spaces

Francesca Arici, Piotr M. Hajac, Mariusz Tobolski

By a diagonal embedding of in , we prolongate the diagonal circle action on the Vaksman-Soibelman quantum sphere to the -action on the prolong…

Reflection positivity in higher derivative scalar theories

Francesca Arici, Daniel Becker, Chris Ripken +2

Reflection positivity constitutes an integral prerequisite in the Osterwalder-Schrader reconstruction theorem which relates quantum field theories defined on Euclidean space to the…

An equivariant pullback structure of trimmable graph C*-algebras

Francesca Arici, Francesco D'Andrea, Piotr M. Hajac +1

We prove that the graph C*-algebra of a trimmable graph is -equivariantly isomorphic to a pullback C*-algebra of a subgraph C*-algebra and the C*-alge…

Quantum lattice gauge fields and groupoid C*-algebras

Francesca Arici, Ruben Stienstra, Walter D. van Suijlekom

We present an operator-algebraic approach to the quantization and reduction of lattice field theories. Our approach uses groupoid C*-algebras to describe the observables and exploi…

Gysin exact sequences for quantum weighted lens spaces

Francesca Arici

We describe quantum weighted lens spaces as total spaces of quantum principal circle bundles, using a Cuntz-Pimsner model. The corresponding Pimsner exact sequence is interpreted a…

The Cuntz-Pimsner extension and mapping cone exact sequences

Francesca Arici, Adam Rennie

For Cuntz-Pimsner algebras of bi-Hilbertian bimodules of finite Jones-Watatani index satisfying some side conditions, we give an explicit isomorphism between the -theory exact s…

Pimsner algebras and circle bundles

Francesca Arici, Francesco D'Andrea, Giovanni Landi

We report on the connections between noncommutative principal circle bundles, Pimsner algebras and strongly graded algebras. We illustrate several results with the examples of quan…

Pimsner algebras and Gysin sequences from principal circle actions

Francesca Arici, Jens Kaad, Giovanni Landi

A self Morita equivalence over an algebra B, given by a B-bimodule E, is thought of as a line bundle over B. The corresponding Pimsner algebra O_E is then the total space algebra o…

The Gysin Sequence for Quantum Lens Spaces

Francesca Arici, Simon Brain, Giovanni Landi

We define quantum lens spaces as `direct sums of line bundles' and exhibit them as `total spaces' of certain principal bundles over quantum projective spaces. For each of these qua…
