Amplification of intrinsic fluctuations by the Lorenz equations

Chaos: An Interdisciplinary Journal of Nonlinear Science, 1993
Macroscopic systems (e.g., hydrodynamics, chemical reactions, electrical circuits, etc.) manifest intrinsic fluctuations of molecular and thermal origin. When the macroscopic dynamics is deterministically chaotic, the intrinsic fluctuations may become amplified by several orders of magnitude. Numerical studies of this phenomenon are presented in detail

Intrinsic Marguerre–von Kármán equations

Mathematics and Mechanics of Solids, 2023
We first show how the classical Marguerre–von Kármán equations modeling the deformation of a nonlinearly elastic shallow shell can be recast as equations whose sole unknowns are the bending moments and stress resultants inside the middle surface of the shell. Thus, these equations allow to compute the stresses inside the shell without having to compute

On The intrinsic equation behind the Delaunay surfaces

AIP Conference Proceedings, 2008
By balancing the internal and external forces acting on axially symmetric membranes one arrives at a system of two equations describing the equilibrium states. This system allows at least two sets of analytical solutions. One of them presents the Euler’s elasticas and the other one can be recognized as the class of Delaunay surfaces.

An algorithm that translates intrinsic equations of curves into intrinsic procedures

International Journal of Mathematical Education in Science and Technology, 1999
The paper describes an algorithm which translates each intrinsic equation of a curve into an intrinsic turtle procedure to draw the same curve. This algorithm inputs an intrinsic equation (or function) of a plane curve of the type ρ = ρ (φ) (where rho is the curvature-radius and φ is the tangent-angle).

Intrinsic geometry of curves and the Lorentz equation

Czechoslovak Journal of Physics, 2002
We show that the trajectory of a point charge in a uniform electromagnetic field is a helix if the Lorentz equation governs its motion. Our approach is totally relativistic, and it is based on the use of the Frenet-Serret formulae which describe the intrinsic geometry of world lines in Minkowski spacetime.

Intrinsic and invariant equations for cosmic string

Il Nuovo Cimento B Series 11, 1994
Taking into account a new definition of the string, the intrinsic and invariant equations verified by the fields are found. Those, quite simple, equations are invariant with respect to the explicit form of the initial Lagrangian.

On the intrinsic connections of systems of partial differential equations. II

Lithuanian Mathematical Journal, 1998
The paper is the continuation of \textit{R. Vosylius} [Lith. Math. J. 38, No. 2, 213-223, (1998; Zbl 0920.35009)]. It treats consistent and structural connections of systems of partial differential equations.

Prologue: The intrinsic Fokker-Planck equation

1980
Examination of equation (3.10) leads us to an interesting conclusion about the classes of FPE (3.1) with non singular diffusion that will represent exactly the same physical content in spite of the fact that they may be written in terms of quite different drifts fν (q) and diffusion tensor D µν (q), related among themselves by general gross variables ...
