Gross-Neveu-Yukawa SO(2) and SO(3) tensorial criticality
SangEun Han, Shouryya Ray, Igor F. Herbut
We investigate the relativistic SO(2)- and SO(3)-invariant Gross-Neveu-Yukawa field theories for real, rank-two, symmetric, traceless tensor order parameters coupled to $N_{\text{f…
The Nordic-walking mechanism and its explanation of deconfined pseudocriticality from Wess-Zumino-Witten theory
Bilal Hawashin, Astrid Eichhorn, Lukas Janssen +2
The understanding of phenomena falling outside the Ginzburg-Landau paradigm of phase transitions represents a key challenge in condensed matter physics. A famous class of examples…
Conjugacy of local homeomorphisms via groupoids and C*-algebras
Becky Armstrong, Kevin Aguyar Brix, Toke Meier Carlsen +1
We investigate dynamical systems consisting of a locally compact Hausdorff space equipped with a partially defined local homeomorphism. Important examples of such systems include s…
Roughsets-based Approach for Predicting Battery Life in IoT
Rajesh Kaluri, Dharmendra Singh Rajput, Qin Xin +4
Internet of Things (IoT) and related applications have successfully contributed towards enhancing the value of life in this planet. The advanced wireless sensor networks and its re…
Shift equivalences through the lens of Cuntz-Krieger algebras
Toke Meier Carlsen, Adam Dor-On, Søren Eilers
Motivated by Williams' problem of measuring novel differences between shift equivalence (SE) and strong shift equivalence (SSE), we introduce three equivalence relations that provi…
Gauge-invariant ideals of C*-algebras of Boolean dynamical systems
Toke Meier Carlsen, Eun Ji Kang
We enlarge the class of -algebras of Boolean dynamical systems in order to include all weakly left-resolving normal labelled space -algebras in it. We prove a gauge-invar…
Condition (K) for Boolean dynamical systems
Toke Meier Carlsen, Eun Ji Kang
We generalize Condition (K) from directed graphs to Boolean dynamical systems and show that a locally finite Boolean dynamical system with countable $…
C*-algebras, groupoids and covers of shift spaces
Kevin Aguyar Brix, Toke Meier Carlsen
To every one-sided shift space we associate a cover , a groupoid and a -algebra …
A Console GRID LA Console GRID Leveraged Authentication and Key Agreement Mechanism for LTE/SAE
Rajakumar Arul, Gunasekaran Raja, Ali Kashif Bashir +2
The growing popularity of multimedia applications, pervasive connectivity, higher bandwidth, and euphoric technology penetration among the bulk of the human race that happens to be…
Orbit equivalence of higher-rank graphs
Toke Meier Carlsen, James Rout
We study the notions of continuous orbit equivalence and eventual one-sided conjugacy of finitely-aligned higher-rank graphs and two-sided conjugacy of row-finite higher-rank graph…
Socially-Aware Congestion Control in Ad-Hoc Networks: Current Status and The Way Forward
Hannan Bin Liaqat, Amjad Ali, Junaid Qadir +3
Ad-hoc social networks (ASNETs) represent a special type of traditional ad-hoc network in which a user's social properties (such as the social connections and communications metada…
Topological freeness for -correspondences
T. M. Carlsen, B. K. Kwasniewski, E. Ortega
We study conditions that ensure uniqueness theorems of Cuntz-Krieger type for relative Cuntz-Pimsner algebras associated to a -correspondence over a $C^…
Cuntz-Krieger algebras and one-sided conjugacy of shifts of finite type and their groupoids
Kevin Aguyar Brix, Toke Meier Carlsen
A one-sided shift of finite type determines on the one hand a Cuntz-Krieger algebra with a distinguished abelian subalgebra and a certai…
Reconstruction of groupoids and C*-rigidity of dynamical systems
Toke Meier Carlsen, Efren Ruiz, Aidan Sims +1
We show how to construct a graded locally compact Hausdorff étale groupoid from a C*-algebra carrying a coaction of a discrete group, together with a suitable abelian subalgebra. W…
Latency Optimal Broadcasting in Noisy Wireless Mesh Networks
Qin Xin, Yan Xia
In this paper, we adopt a new noisy wireless network model introduced very recently by Censor-Hillel et al. in [ACM PODC 2017, CHHZ17]. More specifically, for a given noise paramet…
Diagonal-preserving graded isomorphisms of Steinberg algebras
Toke Meier Carlsen, James Rout
We study Steinberg algebras constructed from ample Hausdorff groupoids over commutative integral domains with identity. We reconstruct (graded) groupoids from (graded) Steinberg al…
The complete classification of unital graph -algebras: Geometric and strong
Søren Eilers, Gunnar Restorff, Efren Ruiz +1
We provide a complete classification of the class of unital graph -algebras - prominently containing the full family of Cuntz-Krieger algebras - showing that Morita equivalenc…
Filtered K-theory for graph algebras
Søren Eilers, Gunnar Restorff, Efren Ruiz +1
We introduce filtered algebraic -theory of a ring relative to a sublattice of ideals. This is done in such a way that filtered algebraic -theory of a Leavitt path algebra…
Diagonal-preserving gauge-invariant isomorphisms of graph -algebras
Toke Meier Carlsen, James Rout
We study graph -algebras equipped with generalised gauge actions, and characterise in terms of groupoids and groupoid cocycles when two graph -algebras are isomorphic by…
Flow equivalence and orbit equivalence for shifts of finite type and isomorphism of their groupoids
Toke Meier Carlsen, Søren Eilers, Eduard Ortega +1
We give conditions for when continuous orbit equivalence of one-sided shift spaces implies flow equivalence of the associated two-sided shift spaces. Using groupoid techniques, we…
Orbit equivalence of graphs and isomorphism of graph groupoids
Toke Meier Carlsen, Marius Lie Winger
We show that the groupoids of two directed graphs are isomorphic if and only if the two graphs are orbit equivalent by an orbit equivalence that preserves isolated eventually perio…
Strong classification of purely infinite Cuntz-Krieger algebras
Toke Meier Carlsen, Gunnar Restorff, Efren Ruiz
In 2006, Restorff completed the classification of all Cuntz-Krieger algebras with finitely many ideals (i.e., those that are purely infinite) up to stable isomorphism. He left open…
Geometric classification of graph -algebras over finite graphs
Søren Eilers, Gunnar Restorff, Efren Ruiz +1
We address the classification problem for graph -algebras of finite graphs (finitely many edges and vertices), containing the class of Cuntz-Krieger algebras as a prominent sp…
Invariance of the Cuntz splice
Søren Eilers, Gunnar Restorff, Efren Ruiz +1
We show that the Cuntz splice induces stably isomorphic graph -algebras.
