We call a piecewise linear mapping from a planar triangulation to the plane a convex combination mapping if the image of every interior vertex is a convex combination of the images of its neighbouring ...

Abstract: A common task in image editing is to change the colours of a picture to match the desired colour grade of another picture. Finding the correct colour mapping is tricky because it involves ...

The ability to map numbers onto a line is universal. But for an Amazonian tribe, this mapping is not linear but logarithmic. The finding illuminates both the nature and the limits of the human ...

The nonconvex problem of minimum curvature is considered in detail and sufficient conditions for existence of solutions as well as characterizations are presented. The L ∞ minimization problem of ...
