Center problem for quartic differential systems with an affine invariant straight line of maximal multiplicity

open access: yesActa et Commentationes: Ştiinţe Exacte şi ale Naturii
In this paper the quartic differential systems with a center-focus critical point and non-degenerate infinity are examined. We show that in this family the maximal multiplicity of an affine invariant straight line is six. Modulo the affine transformation

Straight-line programs with memory and matrix Bruhat decomposition

open access: yes, 2013
We advocate that straight-line programs designed for algebraic computations should be accompanied by a comprehensive complexity analysis that takes into account both the number of fundamental algebraic operations needed, as well as memory requirements ...

La linea sacra di S. Michele e la sfericità terrestre

open access: yesGEOmedia, 2022
According to several sources, not from the cartographic world, the Sacred Line of San Michele unites seven dedicated shrines to the Archangel, from Ireland to Israel, with a mysterious and suggestive straight line.

Line Defects in One-Dimensional Hexagonal Quasicrystals

open access: yesMathematics
Using the eight-dimensional framework of the integral formalism of one-dimensional quasicrystals, the analytical expressions for the displacement fields and stress functions of line defects, which are dislocations and line forces, in one-dimensional ...

The Straight-Line Depreciation is Wanted, Dead or Alive [PDF]

open access: yes
We propose a simple axiomatic system that any depreciation method¡ªcomplying with the core of the accounting of depreciation¡ªmust obey. We show that, while none of the prevalent depreciation methods (e.g., straight-line) ex ante conforms to these ...

Integrability and Wilson loops: the wavy line contour

open access: yes, 2013
The Wilson loop with a wavy line contour is studied using integrable methods. The auxiliary problem is solved and the Lax operator is built to first order in perturbation theory, considering a small perturbation from the straight line.
