KO-Rings of Full Flag Varieties [PDF]
, 2014 We present type-independent computations of the KO-groups of full flag varieties, i.e. of quotient spaces G/T of compact Lie groups by their maximal tori. Our main tool is the identification of the Witt ring, a quotient of the KO-ring, of these varieties

Quantum Drinfeld Hecke Algebras
, 2013 We consider finite groups acting on quantum (or skew) polynomial rings. Deformations of the semidirect product of the quantum polynomial ring with the acting group extend symplectic reflection algebras and graded Hecke algebras to the quantum setting ...

The basic geometry of Witt vectors, I: The affine case [PDF]
, 2015 We give a concrete description of the category of etale algebras over the ring of Witt vectors of a given finite length with entries in an arbitrary ring.

q-deformations of statistical mechanical systems and motives over finite fields [PDF]
, 2017 We consider q-deformations of Witt rings, based on geometric operations on zeta functions of motives over finite fields, and we use these deformations to construct q-analogs of the Bost-Connes quantum statistical mechanical system.

Biological Reviews, EarlyView.ABSTRACT Oropharyngeal food processing exhibits a remarkable diversity among vertebrates, reflecting the evolution of specialised ‘processing centres’ associated with the mandibular, hyoid, and branchial arches. Although studies have detailed various food‐processing strategies and mechanisms across vertebrates, a coherent and comprehensive terminology ...

Constructing Witt–Burnside rings
Advances in Mathematics, 2006 The main theorem of this paper describes an isomorphism between the Witt-Burnside ring over a commutative monoid ring \({\mathbb Z}[M]\) and the Grothendieck ring of a category whose objects are almost finite \(G\)-sets \(X\) for a profinite group \(G\), equipped with a map \(X\rightarrow M\), that is constant on \(G\)-orbits.

ESC Heart Failure, Volume 12, Issue 2, Page 1119-1131, April 2025.Abstract Large clinical data underscore that heart failure is independently associated to an increased risk of negative cognitive outcome and dementia. Emerging evidence suggests that cerebral hypoperfusion, stemming from reduced cardiac output and vascular pathology, may contribute to the largely overlapping vascular dementia and Alzheimer's disease ...

On the Structure of Weyl-Type, Witt-Type, and Non-Associative Algebras over Expolynomial Rings
MathematicsThis paper introduces a generalized class of Weyl-type, Witt-type, and non-associative algebras constructed over an exponential–polynomial (expolynomial) framework.

Semiorderings and Witt rings [PDF]
Bulletin of the Australian Mathematical Society, 2003 For a pythagorean fieldFwith semiorderingQand associated preorderingT, it is shown that the Witt ringWT(F) is isomorphic to the Witt ringW(K) whreKis a closure ofFwith respect toQ. For an arbitrary preorderingT, it is shown how the covering number ofTrelates to the construction ofWT(F).

Epilepsia, EarlyView.Abstract Objective Conceptualizing functional/dissociative seizures (FDS) as resulting from dissociation, or conversion, we hypothesized that, compared to epileptic seizures (ES), FDS should carry more symbolic or communicative content and that this would allow observers to distinguish FDS from ES.
