Highest weight categories arising from Khovanov's diagram algebra II: Koszulity

, 2009
This is the second of a series of four articles studying various generalisations of Khovanov's diagram algebra. In this article we develop the general theory of Khovanov's diagrammatically defined "projective functors" in our setting.

Persuasion in the political marketplace: How firms snitch on rivals to encourage regulatory enforcement

Strategic Management Journal, EarlyView.
Abstract Research Summary We study an important, but largely overlooked, non‐market strategy used by firms in the enforcement stage of policy: “snitching,” that is, providing intelligence about potential violations of their rivals in an attempt to persuade regulators to fine them.

Relative Auslander–Reiten sequences for quasi-hereditary algebras [PDF]

Colloquium Mathematicum, 2002
Summary: Let \(A\) be a finite-dimensional algebra which is quasi-hereditary with respect to the poset \(({\Lambda},\leq)\), with standard modules \(\Delta(\lambda)\) for \(\lambda \in\Lambda\). Let \({\mathcal F}(\Delta)\) be the category of \(A\)-modules which have filtrations where the quotients are standard modules.

A Universal Meta‐Heuristic Framework for Influence Maximisation in Hypergraphs

CAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT Influence maximisation (IM) aims to select a small number of nodes that are able to maximise their influence in a network and covers a wide range of applications. Despite numerous attempts to provide effective solutions in simple networks, higher‐order interactions between entities in various real‐world systems are usually not taken into ...

A pairing in homology and the category of linear complexes of tilting modules for a quasi-hereditary algebra

, 2004
We show that there exists a natural non-degenerate pairing of the homomorphism space between two neighbor standard modules over a quasi-hereditary algebra with the first extension space between the corresponding costandard modules and vise versa ...

Influence of Arc Faults on Pressure Production Characteristics in AC Turret of UHV Transformers

High Voltage, EarlyView.
ABSTRACT The overpressure caused by arc fault in the oil tank can lead to a transformer explosion. Since the AC turret of transformers serves to connect the transformer windings with the AC busbar, the arc current can be extremely high if an earth fault arc occurs leading to potentially hazardous pressure.

Ringel duality and Auslander-Dlab-Ringel algebras

, 2017
We introduce a new class of quasi-hereditary algebras, containing in particular the Auslander-Dlab-Ringel (ADR) algebras. We show that this new class of algebras is preserved under Ringel duality, which determines in particular explicitly the Ringel dual

Time‐resolved XPCS analysis across broad time‐scales using multi‐tau two‐time correlations

Journal of Synchrotron Radiation, EarlyView.
A scalable multi‐tau two‐time correlation framework enables efficient, time‐resolved XPCS analysis of long duration high‐frame‐rate modern synchrotron data while preserving sensitivity to non‐stationary dynamics.We present a multi‐tau two‐time correlation (MT‐2TC) analysis for X‐ray photon correlation spectroscopy that enables efficient analysis of ...

An extension of the basic local independence model to multiple observed classifications

British Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract The basic local independence model (BLIM) is appropriate in situations where populations do not differ in the probabilities of the knowledge states and the probabilities of careless errors and lucky guesses of the items. In some situations, this is not the case. This work introduces the multiple observed classification local independence model

Properly stratified algebras and tilting

, 2005
We study the properties of tilting modules in the context of properly stratified algebras. In particular, we answer the question when the Ringel dual of a properly stratified algebra is properly stratified itself, and show that the class of properly ...
