On the Homothety Conjecture [PDF]
Indiana University Mathematics Journal, 2009 Let K be a convex body in R n and > 0. The homothety conjecture asks: Does K = cK imply that K is an ellipsoid? Here K is the (convex) oating body and c is a constant depending on only.

Children’s first handwriting productions show a rhythmic structure [PDF]
Scientific Reports, 2017 Although much research has been concerned with the development of kinematic aspects of handwriting, little is known about the development along with age of two principles that govern its rhythmic organization: Homothety and Isochrony.

On a class of topological conjugacy with a homothety
Zhurnal Srednevolzhskogo Matematicheskogo Obshchestva, 2020 We consider a class H(Rn) of orientation-preserving homeomorphisms of Euclidean space Rn such that for any homeomorphism h∈H(Rn) and for any point x∈Rn a condition limn→+∞hn(x)→O holds, were O is the origin.

Electronics Letters, 2016 The pinched hysteresis loops drawn in the voltage–current, voltage–charge, and flux–current characteristics belong to well-known fingerprints of the memory elements known as the memristor, memcapacitor, and meminductor.

Homotheties and incidences [PDF]
Discrete Mathematics, 2018 We consider problems involving rich homotheties in a set S of n points in the plane (that is, homotheties that map many points of S to other points of S). By reducing these problems to incidence problems involving points and lines in R^3, we are able to obtain refined and new bounds for the number of rich homotheties, and for the number of distinct ...

Angels' staircases, Sturmian sequences, and trajectories on homothety surfaces [PDF]
Journal of Modern Dynamics, 2018 A homothety surface can be assembled from polygons by identifying their edges in pairs via homotheties, which are compositions of translation and scaling. We consider linear trajectories on a 1-parameter family of genus-2 homothety surfaces.

Some Properties of the χ-Curvature under Conformal Transformation
Mathematics, 2023 In this paper, we identify the sufficient and necessary conditions for conformally related Randers metrics to have the same χ-curvature. Further, if s0=0 holds, we conclude that the conformal transformation must be a homothety.

On Some Problem for a Simplex and a Cube in Rⁿ
Моделирование и анализ информационных систем, 2013 Let S be a nondegenerate simplex in Rⁿ. Denote by α(S) the minimal σ > 0 such that the unit cube Qn:= [0, 1]ⁿ is contained in a translate of σS. In the case α(S) ≠ 1 the translate of α(S)S containing Qn is a homothetic copy of S with the homothety ...
