Going in Circles: Variations on the Money-Coutts Theorem
نویسندگان
چکیده
Given a polygon A1, . . . , An, consider the chain of circles: S1 inscribed in the angle A1, S2 inscribed in the angle A2 and tangent to S1, S3 inscribed in the angle A3 and tangent to S2, etc. We describe a class of n-gons for which this process is 2n-periodic. We extend the result to the case when the sides of a polygon are arcs of circles. The case of triangles is known as the Money-Coutts theorem. Mathematics Subject Classifications (2000): 51M04, 14N99.

Poncelet Theorems
The aim of this note is to collect some more or less classical theorems of Poncelet type and to provide them with short modern proofs. Where classical geometers used elliptic functions (or angular functions), we use elliptic curves (or degenerate elliptic curves decomposing into two rational curves). In this way we unify the geometry underlying these Poncelet type statements. Our starting point...
متن کاملVariational principles for circle patterns and Koebe’s theorem
The subject of this paper is a special class of configurations, or patterns, of intersecting circles in constant curvature surfaces. The combinatorial aspect of such a pattern is described by a cellular decomposition of the surface. The faces of the cellular decomposition correspond to circles and the vertices correspond to points where circles intersect. (See figures 1 and 2.) In the most gene...
متن کاملThe extremal spheres theorem
Consider a polygon P and all neighboring circles (circles going through three consecutive vertices of P ). We say that a neighboring circle is extremal if it is empty (no vertices of P inside) or full (no vertices of P outside). It is well known that for any convex polygon there exist at least two empty and at least two full circles, i.e. at least four extremal circles. In 1990 Schatteman consi...
متن کاملBivariate mean value interpolation on circles of the same radius
We consider bivariate mean-value interpolationproblem, where the integrals over circles are interpolation data. In this case the problem is described over circles of the same radius and with centers are on astraight line and it is shown that in this case the interpolation is not correct.
متن کاملThe Effectiveness of Monetary Policy in Africa: Modeling the Impact of Financial Inclusion
Abstract This study uses annual data over the period 2005-2014 and the Panel VECM approach to examine financial inclusion and monetary policy effectiveness in Africa. The study shows that financial inclusion and monetary policy effectiveness are linked by a set of long-run relationships. Policy reaction to the positive financial inclusion shock is not significant. Policy reaction to the posit...
