Semilinear clannish algebras

open access: yesProceedings of the London Mathematical Society, Volume 129, Issue 4, October 2024.
Abstract We define a class of associative algebras generalizing ‘clannish algebras’, as introduced by the second author, but also incorporating semilinear structure, like a skew polynomial ring. Clannish algebras generalize the well‐known ‘string algebras’ introduced by Butler and Ringel.

Perfectness of a graph associated with annihilating ideals of a ring

open access: yes, 2018
Let [Formula: see text] be a commutative ring with identity which is not an integral domain. An ideal [Formula: see text] of a ring [Formula: see text] is called an annihilating ideal if there exists [Formula: see text] such that [Formula: see text ...

Link splitting deformation of colored Khovanov–Rozansky homology

open access: yesProceedings of the London Mathematical Society, Volume 129, Issue 3, September 2024.
Abstract We introduce a multiparameter deformation of the triply‐graded Khovanov–Rozansky homology of links colored by one‐column Young diagrams, generalizing the “y$y$‐ified” link homology of Gorsky–Hogancamp and work of Cautis–Lauda–Sussan. For each link component, the natural set of deformation parameters corresponds to interpolation coordinates on ...

THE ANNIHILATING-IDEAL GRAPH OF COMMUTATIVE RINGS I

open access: yes, 2011
Let R be a commutative ring, with 𝔸(R) its set of ideals with nonzero annihilator. In this paper and its sequel, we introduce and investigate the annihilating-ideal graph of R, denoted by 𝔸𝔾(R).

TomoPyUI: a user‐friendly tool for rapid tomography alignment and reconstruction

open access: yesJournal of Synchrotron Radiation, Volume 31, Issue 4, Page 979-986, July 2024.
In this study, we introduce TomoPyUI, a user‐friendly interface for the TomoPy tomography data processing package, designed to streamline and enhance the management of synchrotron and neutron computed tomography data. TomoPyUI, operating within a Jupyter environment, incorporates GPU‐accelerated algorithms and a structured data management system ...

Total graph of a module with respect to singular submodule

open access: yes, 2016
Let R be a commutative ring with unity and M be an R-module. We introduce the total graph of a module M with respect to singular submodule Z(M) of M as an undirected graph T(Γ(M)) with vertex set as M and any two distinct vertices x and y are adjacent if

MD-GCN: A Multi-Scale Temporal Dual Graph Convolution Network for Traffic Flow Prediction

open access: yes, 2023
The spatial–temporal prediction of traffic flow is very important for traffic management and planning. The most difficult challenges of traffic flow prediction are the temporal feature extraction and the spatial correlation extraction of nodes. Due

Stabilization distance bounds from link Floer homology

open access: yesJournal of Topology, Volume 17, Issue 2, June 2024.
Abstract We consider the set of connected surfaces in the 4‐ball with boundary a fixed knot in the 3‐sphere. We define the stabilization distance between two surfaces as the minimal g$g$ such that we can get from one to the other using stabilizations and destabilizations through surfaces of genus at most g$g$.

On the connectivity of the annihilating-ideal graphs

open access: yes, 2015
Let R be a commutative ring with identity and *(R) the set of non-zero ideals with non-zero annihilators. The annihilating-ideal graph of R is defined as the graph (R) with the vertex set *(R) and two distinct vertices I₁ and I₂ are adjacent if and only ...
