Tutte's barycenter method applied to isotopies
نویسندگان
چکیده
This paper is concerned with applications of Tutte’s barycentric embedding theorem (1963, Proc. London Math. Soc. 13, 743–768). It presents a method for building isotopies of triangulations in the plane, based on Tutte’s theorem and the computation of equilibrium stresses of graphs by Maxwell–Cremona’s theorem; it also provides a counterexample showing that the analogue of Tutte’s theorem in dimension 3 is false.

متن کاملStochastic Wasserstein Barycenters
We present a stochastic algorithm to compute the barycenter of a set of probability distributions under the Wasserstein metric from optimal transport. Unlike previous approaches, our method extends to continuous input distributions and allows the support of the barycenter to be adjusted in each iteration. We tackle the problem without regularization, allowing us to recover a sharp output whose ...

This paper introduces a novel application in bibliometrics of the barycenter method. Using places of publication barycenters, we measure internationalization of book publishing in the Social Sciences and Humanities. Based on 2002-2011 data for Flanders, Belgium, we demonstrate how the geographic center of weight of book publishing is different for the Social Sciences than for the Humanities. Wh...
متن کاملGeometry of Fisher Information Metric and the Barycenter Map
Geometry of Fisher metric and geodesics on a space of probability measures defined on a compact manifold is discussed and is applied to geometry of a barycenter map associated with Busemann function on an Hadamard manifold X . We obtain an explicit formula of geodesic and then several theorems on geodesics, one of which asserts that any two probability measures can be joined by a unique geodesi...
متن کاملApplication of Barycenter Refined Meshes in Linear Elasticity and Incompressible Fluid Dynamics
The paper demonstrates that enhanced stability properties of some finite element methods on barycenter refined meshes enables efficient numerical treatment of problems involving incompressible or nearly incompressible media. One example is the linear elasticity problem in a pure displacement formulation, where a lower order finite element method is studied which is optimal order accurate and ro...
