,S?kulare Aenderungen der Sicht,ivariable setting. Additionally, we show a variety of applications of the Quantitative BLT, proving in particular nonsymmetric BLTs in both the discrete and continuous setting for functions with more than one argument. Finally, in direct analogy of the continuous setting, we show the Quantitative Finite BLT implies the Finite BLT.

On Eigenvalue Distribution of Varying Hankel and Toeplitz Matrices with Entries of Power Growth or We study the distribution of eigenvalues of varying Toeplitz and Hankel matrices such as . and . where .. behaves roughly like .. for some non- 0 complex number ., and .?→.. This complements earlier work on these matrices when the coefficients . arise from entire functions.

On the Gradient Conjecture for Quadratic Polynomials,The gradient conjecture asserts that for homogeneous polynomials . and . the equality .(?.)?=?0 implies .(?).?=?0. We verify this conjecture for quadratic polynomials and present a few applications to density problems and characterization of derivation operator.

Non-stationary Subdivision Schemes: State of the Art and Perspectives,ete data, by repeated level dependent linear refinements. In particular the paper emphasises the potentiality of these schemes and the wide perspective they open, in comparison with stationary schemes based on level-independent linear refinements.
