Invariants and Coinvariants of the Symmetric Group in Noncommuting Variables
, 2005 We introduce a natural Hopf algebra structure on the space of noncommutative symmetric functions which was recently studied as a vector space by Rosas and Sagan. The bases for this algebra are indexed by set partitions. We show that there exist a natural

Noncommutative Bessel symmetric functions
, 2006 The consideration of tensor products of 0-Hecke algebra modules leads to natural analogs of the Bessel J-functions in the algebra of noncommutative symmetric functions. This provides a simple explanation of various combinatorial properties of Bessel functions.

Antipode formulas for some combinatorial Hopf algebras
, 2016 Motivated by work of Buch on set-valued tableaux in relation to the K-theory of the Grassmannian, Lam and Pylyavskyy studied six combinatorial Hopf algebras that can be thought of as K-theoretic analogues of the Hopf algebras of symmetric functions ...

Odd Jacobi Manifolds and Loday-Poisson Brackets
Journal of Mathematics, 2014 We construct a nonskew symmetric version of a Poisson bracket on the algebra of smooth functions on an odd Jacobi supermanifold. We refer to such Poisson-like brackets as Loday-Poisson brackets.

Smoothed one-core and core–multi-shell regular black holes
European Physical Journal C: Particles and Fields, 2018 We discuss the generic properties of a general, smoothly varying, spherically symmetric mass distribution $$\mathcal {D}(r,\theta )$$ D(r,θ) , with no cosmological term ($$\theta $$ θ is a length scale parameter).

String Geometry and the Noncommutative Torus [PDF]
, 1998 We construct a new gauge theory on a pair of d-dimensional noncommutative tori. The latter comes from an intimate relationship between the noncommutative geometry associated with a lattice vertex operator algebra A and the noncommutative torus.

UV/IR mixing and the Goldstone theorem in noncommutative field theory [PDF]
, 2002 Noncommutative IR singularities and UV/IR mixing in relation with the Goldstone theorem for complex scalar field theory are investigated. The classical model has two coupling constants, $\lambda_1$ and $\lambda_2$, associated to the two noncommutative ...

Quantum Frustration as a Protection Mechanism in Non‐Topological Majorana Qubits
Annalen der Physik, Volume 538, Issue 4, April 2026.Quantum frustration is proposed as a robust protection mechanism for non‐topological ‐junction qubit. By leveraging distinct spatial profiles, co‐located Majorana modes couple to independent environments, creating incompatible pointer bases that suppress decoherence.
