Higher spins, quadratic forms and amplitudes
Journal of High Energy Physics, 2020 The light-cone Hamiltonians for spin 1 and spin 2 fields, describing both the pure and the maximally supersymmetric theories, may be expressed as quadratic forms. In this paper, we show that this feature extends to light-cone higher spin theories.

On the Moment Problem and Related Problems
Mathematics, 2021 Firstly, we recall the classical moment problem and some basic results related to it. By its formulation, this is an inverse problem: being given a sequence (yj)j∈ℕn of real numbers and a closed subset F⊆ℝn, n∈{1,2,…}, find a positive regular Borel ...

Effective Density for Inhomogeneous Quadratic Forms I: Generic Forms and Fixed Shifts [PDF]
, 2019 We establish effective versions of Oppenheim's conjecture for generic inhomogeneous quadratic forms. We prove such results for fixed shift vectors and generic quadratic forms.

An Introduction to some Methods for Solving A Large System Linear Neutrosophic Equations [PDF]
Neutrosophic Sets and Systems, 2023 This paper aims to extend the methods of steepest descent and conjugate directions to the neutrosophic field R(I). the generalizations were built similarly to the classic algorithms, starting by generalizing the quadratic forms to R(I).

Quadratic structures associated to (multi)rings [PDF]
Categories and General Algebraic Structures with Applications, 2022 We consider certain pairs (A, T) where A is a (multi)ring andT ⊆ A is a multiplicative set that generates, by a convenient quotient construction,a (multi)structure that supports a quadratic form theory: withsome natural hypotheses we generalize ...

Euclidean Quadratic Forms and ADC Forms I [PDF]
, 2011 Motivated by classical results of Aubry, Davenport and Cassels, we define the notion of a Euclidean quadratic form over a normed integral domain and an ADC form over an integral domain.

Arithmetic progressions in binary quadratic forms and norm forms [PDF]
, 2019 We prove an upper bound for the length of an arithmetic progression represented by an irreducible integral binary quadratic form or a norm form, which depends only on the form and the progression's common difference.
