The new Riemannian color model, however, accounted for how humans perceive those color differences accurately using three-dimensional curves rather than flat Euclidean vectors.

This paper proves that for every convex body in Rn there exist 5n Minkowski symmetrizations which transform the body into an approximate Euclidean ball. This result complements the sharp cn log n ...

We compare the hausdorff measures and dimensions with respect to the Euclidean and Heisenberg metrics on the first Heisenberg group. The result is a dimension jump described by two inequalities. The ...
