Selfsimilarity and growth in Birkhoff sums for the golden rotation

, 2010
We study Birkhoff sums S(k,a) = g(a)+g(2a)+...+g(ka) at the golden mean rotation number a with periodic continued fraction approximations p(n)/q(n), where g(x) = log(2-2 cos(2 pi x).

A derivation of coincidence relations utilizing quaternion and matrix based on the hexagonal lattice for material engineers

International Journal of Mathematics for Industry, 2019
Grain-oriented silicon steel is mainly used as the core material of transformers, and it is manufactured by applying secondary recrystallization. The driving force of this process is the grain boundary energy, based on the nature of the grain boundary ...

Mathematical study of rotating fluids with resonant surface stress

Journal of Differential Equations, 2009
AbstractWe are interested here in describing the linear response of a highly rotating fluid to some surface stress tensor, which admits fast time oscillations and may be resonant with the Coriolis force. In addition to the usual Ekman layer, we exhibit another – much larger – boundary layer, and we prove that for large times, the effect of the surface ...

Visual Form Perception Can Be a Cognitive Correlate of Lower Level Math Categories for Teenagers

Frontiers in Psychology, 2017
Numerous studies have assessed the cognitive correlates of performance in mathematics, but little research has been conducted to systematically examine the relations between visual perception as the starting point of visuospatial processing and typical ...
