On the Q $Q$‐Polynomial Property of Bipartite Graphs Admitting a Uniform Structure
Journal of Combinatorial Designs, EarlyView.ABSTRACT Let Γ ${\rm{\Gamma }}$ denote a finite, connected graph with vertex set X $X$. Fix x ∈ X $x\in X$ and let ε ≥ 3 $\varepsilon \ge 3$ denote the eccentricity of x $x$. For mutually distinct scalars { θ i * } i = 0 ε ${\{{\theta }_{i}^{* }\}}_{i=0}^{\varepsilon }$ define a diagonal matrix A * = A * ( θ 0 * , θ 1 * , … , θ ε * ) ∈ Mat X ( R ) ${A}^

On the Analytic Structure of Commutative Nilmanifolds [PDF]
, 2014 In the classification theorems of Vinberg and Yakimova for commutative nilmanifolds, the relevant nilpotent groups have a very surprising analytic property.

On the section conjecture over fields of finite type
Mathematische Nachrichten, EarlyView.Abstract Assume that the section conjecture holds over number fields. We prove then that it holds for a broad class of curves defined over finitely generated extensions of Q$\mathbb {Q}$. This class contains every projective, hyperelliptic curve, every hyperbolic, affine curve of genus ≤2$\le 2$, and a basis of open subsets of any curve.

Commutative Encryption and Data Hiding in HEVC Video Compression
IEEE Access, 2019 In this paper, an efficient commutative encryption and data hiding scheme for HEVC videos is proposed. The commutative property allows ciphering a steganographic video without interfering with the embedded signal or to perform steganography on an ...

Commutativity properties of Quinn spectra
Proceedings of the Royal Society of Edinburgh: Section A MathematicsWe give a simple sufficient condition for Quinn’s ‘bordism-type’ spectra to be weakly equivalent to commutative symmetric ring spectra. We also show that the symmetric signature is (up to weak equivalence) a monoidal transformation between symmetric monoidal functors, which implies that the Sullivan–Ranicki orientation of topological bundles is ...

The domination theorem for operator classes generated by Orlicz spaces
Mathematische Nachrichten, EarlyView.Abstract We study lattice summing operators between Banach spaces focusing on two classes, ℓφ$\ell _\varphi$‐summing and strongly φ$\varphi$‐summing operators, which are generated by Orlicz sequence lattices ℓφ$\ell _\varphi$. For the class of strongly φ$\varphi$‐summing operators, we prove the domination theorem, which complements Pietsch's ...

Some ergodic properties of commuting diffeomorphisms [PDF]
Ergodic Theory and Dynamical Systems, 1993 AbstractFor a smooth ℤ2-action on a C∞ compact Riemannian manifold M, we discuss its ergodic properties which include the decomposition of the tangent space of M into subspaces related to Lyapunov exponents, the existence of Lyapunov charts, and the subadditivity of entropies.

An Inverse Source Technique as a Preliminary Tool to Localize Persons in Indoor Spaces
Mathematical Methods in the Applied Sciences, EarlyView.ABSTRACT This paper considers an inverse heat source localization problem with applications to indoor person localization from temperature measurements. In particular, this inverse problem consists in the reconstruction of the intensity and position of heat sources from observed temperature data.

Some properties of the commutator of two operators
Journal of Mathematical Analysis and Applications, 1968 1. Consider a Banach space X and let B(X) be the algebra of linear- bounded operators on 3Z. If T, S, X E B(3E) we may define on B(X) the opera- tor C( T, S) X = TX - XS, which is often called the commutator of T and S. We denote px(T, S) = !E /I C(T, S)n X jjlln.

Fully Quantum Perturbative Description of Correlated Stokes–Anti‐Stokes Scattering
physica status solidi (b), EarlyView.The generation of Stokes‐anti‐Stokes (SaS) photon pairs with quantum correlations, like entanglement, has been developing recently, but a proper theoretical ground was missing. A fully quantum perturbative theory is provided to describe the four‐wave mixing contribution to the correlated SaS scattering, in which both matter and electromagnetic field ...
