Modules as exact functors
We can define a module to be an exact functor on a small abelian category.
This is explained and shown to be equivalent to the usual definition but it
does offer a different perspective, inspired by the notions from model theory
of imaginary sort and interpretation. A number of examples are worked through
Multisorted modules and their model theory
Multisorted modules, equivalently representations of quivers, equivalently
additive functors on preadditive categories, encompass a wide variety of
additive structures. In addition, every module has a natural and useful
multisorted extension by imaginaries. The model theory of multisorted modules
works just as for the usual, 1-sorted modules. A number of examples are
presented, some in considerable detail
Where are the vrais dévots and are they véritables gens de bien? Eloquent slippage in the Tartuffe controversy
The famous controversy provoked by Molière’s Tartuffe (1664–1669) is usually read in terms of vrais and faux dévots and thought to turn on the question of sincerity versus hypocrisy. Here the vrai-faux dichotomy is challenged and a third term introduced in the form of the véritable homme de bien of Molière’s Preface to the published edition of the play. In the slippage between a vrai dévot and a véritable homme de bien (considered by most critics to be synonymous), I argue, lies a value-judgment and the suggestion of an alternative, more secular worldview that persisted even in the 1669 version of the play. The scandal of Tartuffe thus lies less with the threat of religious hypocrisy and more with the possibility that true morality could be found outside the Church.PostprintPeer reviewe
Ringel's conjecture for domestic string algebras
We classify indecomposable pure injective modules over domestic string
algebras, verifying Ringel's conjecture on the structure of such modules.Comment: minor correction
Modules with irrational slope over tubular algebras
Let be a tubular algebra and let be a positive irrational. Let
be the definable subcategory of -modules of slope . Then
the width of the lattice of pp formulas for is . It
follows that if is countable then there is a superdecomposable
pure-injective module of slope .Comment: minor corrections/improvements to argument
The road to Prest v Petrodel: an analysis of the UK judicial approach to the corporate veil - part 2: post Prest
This article examines the judicial approach to the corporate veil post-Prest v Petrodel Resources Ltd. Analysis is undertaken of the judgment in Prest and of how judges have adapted and applied this judgment in subsequent cases. The article offers an evaluation on whether the judgment in Prest, has indeed, provided much needed clarity on the judicial approach to the concealment/evasion principles as grounds for veil-piercing/lifting. The article concludes by advocating for a return to the use of the doctrine of judicial discretion as a tool for addressing legal matters relating to the corporate veil of incorporation
