Sharp Upper Bound for Amplitudes of Finite‐Gap Solutions of the Modified Korteweg‐de Vries Equation
Studies in Applied Mathematics, Volume 157, Issue 3, September 2026.ABSTRACT A sharp upper bound is established for the amplitudes of finite‐gap solutions of the focusing modified Korteweg–de Vries equation. The proof shows that the optimization can be carried out entirely within the finite‐dimensional hierarchy, without explicit integration of the finite‐gap solution. The maximal amplitude is expressed in terms of the

Pinwheels in symplectic rational and ruled surfaces and non‐squeezing of rational homology balls
Journal of Topology, Volume 19, Issue 3, September 2026.Abstract We use almost toric fibrations and the symplectic rational blow‐up to determine when certain Lagrangian pinwheels, which we call liminal, embed in symplectic rational and ruled surfaces. The case of L2,1$L_{2,1}$‐pinwheels, namely Lagrangian RP2s$\mathbb {R}P^2{\rm s}$, answers a question of Kronheimer in the negative, exhibiting a symplectic ...

Construction of Commutator Blueprints [PDF]
Commutator blueprints can be seen as blueprints for constructing RGD-systems over $\mathbb{F}_2$ with prescribed commutation relations. In this paper we construct several families of Weyl-invariant commutator blueprints, mostly of universal type ...

Commutator anomaly for the Gauss law constraint operator
Nuclear Physics B, 1986 Abstract A formula useful for evaluating the commutator anomaly for the Gauss law constraint operator is presented. This formula makes the perturbative calculation of the anomaly much simpler than previous attempts. Furthermore, the commutator anomaly is shown to be derived directly from the non-abelian chiral anomaly and the perturbative calculation

Dynamics of the Commutator Operator [PDF]
, 2014 Linear dynamics is a rapidly evolving area of operator theory, however the only results related to the dynamics of the commutator operators have hitherto been on the characterisation of the hypercyclicity of the left and right multiplication operators.

On the ternary commutator, I: Exact Mal'tsev categories,
, 2021 In this first article on the Bulatov commutator, we introduce a ternary commutator of equivalence relations in the context of an exact Mal'tsev category with binary coproducts. We prove that, for Mal'tsev varieties, our notion is a particular case (where

An exciting Approach to Theoretical Spectroscopy
Advanced Science, Volume 13, Issue 47, 24 August 2026.ABSTRACT Theoretical spectroscopy, and more generally, electronic‐structure theory, are powerful concepts for describing the complex many‐body interactions in materials. They cover methods from ground‐state properties to lattice excitations and light‐matter interaction, including time‐resolved variants.

On Commutativity of Rings Under Certain Polynomial Constraints [PDF]
International Journal of Data Science and Analysis, 2018 The pioneer theorem of Weddernburn on commutativity of division rings was proved in the very beginning of twentieth century. Aside from its own intrinsic beauty and important role in many diverse parts of algebra specially, the theorem serves as the starting point for investigations of certain kinds of conditions that render a ring commutative. A large

CNS Neuroscience &Therapeutics, Volume 32, Issue 8, August 2026.This study examined how propofol‐supported recovery sleep shapes cognitive and sleep‐EEG outcomes after 48‐h SD. Rats received Barnes maze, 2‐h and 24‐h NOR testing, cortical EEG/EMG recording, and NKCC1/KCC2 expression analysis. Propofol increased slow‐oscillation density and restored precise SO–spindle alignment, accompanied by a shift in NKCC1/KCC2 ...

The Huang–Yang Formula for the Low‐Density Fermi Gas: Upper Bound
Communications on Pure and Applied Mathematics, Volume 79, Issue 8, Page 1919-1972, August 2026.ABSTRACT We study the ground state energy of a gas of spin 1/2$1/2$ fermions with repulsive short‐range interactions. We derive an upper bound that agrees, at low density ϱ$\varrho$, with the Huang–Yang conjecture. The latter captures the first three terms in an asymptotic low‐density expansion, and in particular the Huang–Yang correction term of order
