Generalized Beth–Uhlenbeck Entropy Formula From the Φ‐Derivable Approach
Contributions to Plasma Physics, EarlyView.ABSTRACT We derive a generalized Beth–Uhlenbeck formula for the entropy of a dense fermion system with strong two‐particle correlations, including scattering states and bound states. We work within the Φ‐derivable approach to the thermodynamic potential.

The asymptotically-free gauge theories
Journal of High Energy PhysicsWe show how to classify the asymptotically-free gauge theories in four spacetime dimensions, focussing here on the case of purely fermionic matter. The classification depends on the fact (which we prove) that the dimension and Dynkin index of irreducible

Irreducible ∗-representations of some group rings and associated Banach ∗-algebras
, 1980 Let G be the group which is a wreath product of two infinite cyclic groups. We construct a faithful, topologically irreducible ∗-representation of l1(G) on l2(Z), and a faithful, strictly irreducible representation on l1(Z).

IRREDUCIBLE REPRESENTATIONS OF HILBERT C-MODULES [PDF]
Mathematical Proceedings of the Royal Irish Academy, 2005 The subject of the paper is representations of Hilbert C*-modules. We introduce the concept of a nondegenerate, irreducible and cyclic representation and the cornmutant of a Hilbert C*-module. Relations between representations of a Hilbert C*-module, its linking algebra and underlying C*-algebras are discussed. We also study Hilbert CCR-and GCR-modules

Cytometry Part A, EarlyView.ABSTRACT Advances in spectral cytometry instrumentation and fluorescent reagents have led to the possibility of ultra‐high‐parameter panels exceeding 50 colors. However, panel size is limited in practice by unmixing‐dependent spreading (UDS), a phenomenon which leads to a progressive deterioration of unmixed signal‐to‐noise ratios in panels that ...

Mixed-symmetry fields in de Sitter space: a group theoretical glance
Journal of High Energy Physics, 2017 We derive the characters of all unitary irreducible representations of the (d+1)-dimensional de Sitter spacetime isometry algebra so 1 , d + 1 $$ \mathfrak{so}\left(1,\kern0.5em d+1\right) $$ , and propose a dictionary between those representations and ...

Computing irreducible representations of finite groups
, 1990 We consider the bit-complexity of the problem stated in the title. Exact computations in algebraic number fields are performed symbolically. We present a polynomial-time algorithm to find a complete set of nonequivalent irreducible representations over ...

Defect‐Engineered SrTiO3‐x for Flexoelectric‐Dominated Catalysis
EcoEnergy, EarlyView.Defect‐engineered SrTiO3‐x nanoparticles with enhanced flexoelectricity efficiently degrade pollutants and produce hydrogen under ultrasound‐driven flexocatalysis. This materials–engineering approach offers a scalable pathway for combining environmental remediation and renewable energy applications. ABSTRACT Flexocatalysis provides an alternative route

On tensor squares of irreducible representations of almost simple groups. I
Моделирование и анализ информационных систем, 2011 Almost simple SM_m-groups are considered. A group G is called a SM_m-group if the tensor square of any irreducible representation is decomposed into the sum of its irreducible representations with multiplicities not greater than m.

Extended BMS representations and strings
Journal of High Energy PhysicsWe construct in detail the irreducible representations of the BMS group with super rotations in three and four dimensions that have the same rest frame momenta as the massive and massless Poincaré point particles.
