Matched wavelets for equidistant points
Elena A. Lebedeva
Matched wavelets interpolating equidistant data are designed. These wavelets form Riesz bases. Meyer wavelets that interpolate data on a particular uniform lattice are found.

Directional Heisenberg uncertainty product
A. Krivoshein, E. Lebedeva, E. Neiman +1
A directional time-frequency localization measure for functions defined on the -dimensional Euclidean space is introduced. A connection between this measure and its periodic cou…

Uncertainty product for Vilenkin groups
Ivan Kovalyov, Elena Lebedeva
We study a localization of functions defined on Vilenkin groups. To measure the localization we introduce two uncertainty products and that are similar to the Heise…
