Boundary Shearlets


Boundary Shearlets


With the introduction of boundary shearlets, the authors Philipp Grohs, Gitta Kutyniok, Jackie Ma, and Philipp Petersen resolve the long-open problem of developing an anisotropic multiscale system on bounded domains \Omega, which form frames for L^2(\Omega) and H^2(\Omega), exhibit vanishing moments, provide optimal sparse approximation for functions that are smooth apart from a curve-like discontinuity, and characterize Sobolev spaces.
