Discrete Carleman Estimates for Elliptic Operators in Arbitrary Dimension and Applications
In arbitrary dimension, we consider the semi-discrete elliptic operator -2 t + AM , where AM is a finite difference approximation of the operator - x((x) x). For this operator we d...

Dual frame of frequency warping operators
In this work we introduce the dual frame operator relative to the aliasing compensated frequency warping operator for nonsmooth warping functions. Except for approximation errors,...

SpectrUW: A laboratory for the numerical exploration of spectra of linear operators
Spectra of linear operators play an important role in various aspects of applied mathematics. For all but the simplest operators, the spectrum cannot be determined analytically an...

Matching Names and Definitions of Topological Operators
In previous empirical work humans did not recognize the definition of most topological operators for regions by their names in two geospatial information systems (GIS). This work d...
