On Hyperbolic Initial-Boundary Value Problems with a Strictly Dissipative Boundary Condition,e regularity assumptions on the coefficients of the differential operator and the boundary condition as well as the boundary itself are quite minimal. Characterizations of strictly dissipative boundary operators are given and the example of Maxwell’s equations is discussed.

Sparse Regularization of Inverse Problems by Operator-Adapted Frame Thresholding,ralizes the SVD. The DFD allows to define a non-iterative (direct) operator-adapted frame thresholding approach which we show to provide a convergent regularization method with linear convergence rates. These results will be compared to the well-known analysis and synthesis variants of sparse ..-reg
