Abelovu cenu za rok 2019 získala Karen Uhlenbecková
Abelovu cenu získala v roce 2019 matematička Karen Uhlenbecková. Její práce mají důležitý dopad hned na několik oborů matematiky - geometrii, analýzu i matematickou fyziku. Zásadním způsobem ovlivnila moderní pojetí geometrické analýzy. V článku se pomocí relativně jednoduchých příkladů snažíme čtenáře seznámit se dvěma z oblastí, kterými se doposud zabývala. Na závěr též velmi stručně zmiňujeme hlavní výsledky několika jejích prací.
About an intermediate point property in some quadrature formulas.
About an inverse eigenvalue problem arising in vibration analysis
About biharmonic problem via a spectral approach and decomposition techniques.
About calculation of the Hankel transform using preliminary wavelet transform.
About Delaunay triangulations and discrete maximum principles for the linear conforming FEM applied to the Poisson equation
The starting point of the analysis in this paper is the following situation: “In a bounded domain in , let a finite set of points be given. A triangulation of that domain has to be found, whose vertices are the given points and which is ‘suitable’ for the linear conforming Finite Element Method (FEM).” The result of this paper is that for the discrete Poisson equation and under some weak additional assumptions, only the use of Delaunay triangulations preserves the maximum principle.
About existence and uniqueness of the restricted total least squares estimation.
About Fejér's sum.
About stability estimates and resolvent conditions
About the deficient spline collocation method for particular differential and integral equations with delay.
About the geometry of milling paths.
About the representation of solutions of linear elliptic equations of arbitrary order
