Extended multi-scalar field theories in (1+1) dimensions [PDF]
Eur. Phys. J. C (2020) 80:1143, 2020 We present the explicit construction of some multi-scalar field theories in (1+1) dimensions supporting BPS (Bogomol'nyi--Prasad--Sommerfield) kink solutions. The construction is based on the ideas of the so-called extension method. In particular, several new interesting two-scalar and three-scalar field theories are explicitly constructed from non ...

SCALAR AND VECTOR IN COMPULATION
Открытое образование (Москва), 2016 The article deals with two fundamental data types – scalar and vector (array), without the ability of working with them one cannot solve using computer school or university tasks in mathematics, physics, chemistry and other technical training courses ...

Aperture referral in dioptric systems with stigmatic elements
African Vision and Eye Health, 2012 A previous paper develops the general theory of aperture referral in linear optics and shows how several ostensibly distinct concepts, including the blur patch on the retina, the effective corneal patch, the projective field and the field of view, are ...

Quantum Reports, 2020 The mathematical similarities between non-relativistic wavefunction propagation in quantum mechanics and image propagation in scalar diffraction theory are used to develop a novel understanding of time and paths through spacetime as a whole.

Stable discontinuous Galerkin FEM without penalty parameters [PDF]
, 2015 We propose a modified local discontinuous Galerkin (LDG) method for second--order elliptic problems that does not require extrinsic penalization to ensure stability.

On a boundary value problem for a Boussinesq-type equation in a triangle
Вестник КазНУ. Серия математика, механика, информатика, 2022 Earlier, we considered an initial-boundary value problem for a one-dimensional Boussinesq-type equation in a domain that is a trapezoid, in which the theorems on its unique weak solvability in Sobolev classes were established by the methods of the theory

A Lagrangian fluctuation-dissipation relation for scalar turbulence, I. Flows with no bounding walls [PDF]
Journal of Fluid Mechanics 829, 153-189 (2017), 2016 An exact relation is derived between scalar dissipation due to molecular diffusivity and the randomness of stochastic Lagrangian trajectories for flows without bounding walls. This "Lagrangian fluctuation-dissipation relation" equates the scalar dissipation for either passive or active scalars to the variance of scalar inputs associated to initial ...
