Forced Convex n -Gons in the Plane [PDF]
Discrete & Computational Geometry, 1998 Denote by \(g(n)\) the smallest number such that every set of \(g(n)\) points in the plane in general position contains the vertices of a convex \(n\)-gon. In 1935 Erdős and Szekeres proved that \[ 2^{n- 2}+ 1\leq g(n)\leq {2n-4\choose n-2}+ 1. \] The authors of the present paper lessen the right estimate by 1.

A Scheme for Solving the Plane–Plane Challenge in Force Measurements at the Nanoscale [PDF]
Nanoscale Research Letters, 2010 Non-contact interaction between two parallel flat surfaces is a central paradigm in sciences. This situation is the starting point for a wealth of different models: the capacitor description in electrostatics, hydrodynamic flow, thermal exchange, the Casimir force, direct contact study, third body confinement such as liquids or films of soft condensed ...

Gain-Sparsity and Symmetry-Forced Rigidity in the Plane [PDF]
Discrete & Computational Geometry, 2016 We consider planar bar-and-joint frameworks with discrete point group symmetry in which the joint positions are as generic as possible subject to the symmetry constraint. We provide combinatorial characterizations for symmetry-forced rigidity of such structures with rotation symmetry or dihedral symmetry of order 2k with odd k, unifying and extending ...

Forcing Disjoint Segments in the Plane
European Journal of Combinatorics, 1996 A geometric graph is a graph drawn in the plane such that its edges are closed line segments and no three vertices are colinear. Denoting by \(n\) the number of vertices and by \(m\) the number of edges, the following hold: (i) if \(m\geq 3n+ 1\), then there exist three pairwise disjoint edges; (ii) if \(m\geq 10n+ 1\), then there exist four pairwise ...

A Note on Forced Oscillations in Systems on a Plane
Nelineinaya Dinamika, 2023 A sufficient condition for the existence of forced oscillations in nonautonomous systems on a plane is presented under the assumption that the magnitude of the nonautonomous perturbation is small. An advantage of the results presented over analytic methods is that they can be applied in degenerate systems as well.

Dynamics driven by lipophilic force in Langmuir monolayers: In-plane and out-of-plane growth [PDF]
Physical Review E, 2015 While monolayer area fraction versus time (A(n)-t) curves obtained from surface pressure-area (π-A) isotherms for desorption-dominated (DD) processes in Langmuir monolayers of fatty acids represent continuous loss, those from Brewster angle microscopy (BAM) also show a two-dimensional (2D) coalescence.
