The dual conformal box integral in Minkowski space
Nuclear Physics B, 2021 The dual conformal box integral in Minkowski space is not fully determined by the conformal invariants z and z¯. Depending on the kinematic region its value is on a ‘branch’ of the Bloch-Wigner function which occurs in the Euclidean case.

The structure of force-free magnetic fields [PDF]
, 2000 Incontrovertible evidence is presented that the force-free magnetic fields exhibit strong stochastic behavior. Arnold’s solution is given with the associated first integral of energy.

Fixed Points for ψ-Graphic Contractions with Application to Integral Equations
Abstract and Applied Analysis, 2013 The aim of this paper is to define modified weak α-ψ-contractive mappings and to establish fixed point results for such mappings defined on partial metric spaces using the notion of triangular α-admissibility.

Engineering Transactions, 2014 An initial stability of Kirchhoff plates is analysed in the paper. Proposed approach avoids Kirchhoff forces at the plate corner and equivalent shear forces at a plate boundary. Two unknown variables are considered at the boundary element node.

Khinchin theorem for integral points on quadratic varieties
, 2008 We prove an analogue the Khinchin theorem for the Diophantine approximation by integer vectors lying on a quadratic variety. The proof is based on the study of a dynamical system on a homogeneous space of the orthogonal group. We show that in this system,

Integral points of Galois covers
Matemática Contemporânea, 1998 Let \(C\) be a smooth projective curve of genus \(g(C)\) defined over the rationals and let \(x\in Q(C)\) be a non-constant rational function on \(C\). Further, let \(C(x,\mathbb{Z})\) be the set of integral points on \(C\), that is points in \(C(\mathbb{Q})\) for which \(x(F)\in\mathbb{Z}\). \textit{C. L. Siegel }'s famous theorem [Abh. Akad.

Integral Representations of Two-Point Functions [PDF]
Physical Review, 1960 An integral representation for a general matrix element of two field operators between eigenstates labelled by an arbitrary number of momenta is presented. This representation is conveniently parametrized over a set of invariants related to the total momentum and momentum transfer, and explicitly incorporates spectral conditions. Physically interesting

On the Approximate Evaluation of Some Oscillatory Integrals
Atoms, 2019 To determine the photon emission or absorption probability for a diatomic system in the context of the semiclassical approximation it is necessary to calculate the characteristic canonical oscillatory integral which has one or more saddle points ...

Positive Fixed Points of Hammerstein Integral Operators with Degenerate Kernel
Учёные записки Казанского университета: Серия Физико-математические наукиPositive fixed points of the Hammerstein integral operators with a degenerate kernel in the space of continuous functions C [0, 1] were explored. The problem of determining the number of positive fixed points of the Hammerstein integral operator was ...
