Orhonormal wavelet bases on the 3D ball via volume preserving map from the regular octahedron

Adrian Holhos, Daniela Rosca

We construct a new volume preserving map from the unit ball $B^{3}$ to the regular 3D octahedron, both centered at the origin, and its inverse. This map will help us to const…

Area preserving maps and volume preserving maps between a class of polyhedrons and a sphere

Adrian Holhoş, Daniela Roşca

For a class of polyhedrons denoted $K_{n} (r, ε)$ , we construct a bijective continuous area preserving map from $K_{n} (r, ε)$ to the sphere $\mathbb S^…

The rate of convergence of some Riemann-Stieltjes sums

Adrian Holhos

We give the rate of convergence of some optimal lower Riemann-Stieltjes sums toward the integral.
