Marcinkiewicz averages of smooth orthogonal projections on sphere
Marcin Bownik, Karol Dziedziul, Anna Kamont
We construct a single smooth orthogonal projection with desired localization whose average under a group action yields the decomposition of the identity operator. For any full rank…

Simultaneous dilation and translation tilings of
Marcin Bownik, Darrin Speegle
We solve the wavelet set existence problem. That is, we characterize the full-rank lattices and invertible matrices for which there exists a…

A characterization of spaces of homogeneous type induced by continuous ellipsoid covers of
Marcin Bownik, Baode Li, Tal Weissblat
We study the relationship between the concept of a continuous ellipsoid cover of , which was introduced by Dahmen, Dekel, and Petrushev, and the space of homogene…
