High order differential functions of several variables are approximated by multivariate shift-invariant convolution type operators and their generalizations. The high order of this approximation is determined by giving some multivariate Jackson-type inequalities, engaging the first multivariate usua

Results on first order Ext groups for Hilbert modules over the disk algebra are used to study certain backward shift invariant operator ranges, namely de Branges Rovnyak spaces and a more general class called H(W ; B) spaces. Necessary and sufficient conditions are given for the groups Ext 1 A(D) (H

For an invertible nΓ—n matrix B and a finite or countable subset of Our main objects of interest in this paper are the kernel of the associated Gramian G(.) and dual Gramian G(.) operator-valued functions. We show in particular that the orthogonal complement of M in L 2 (R n ) can be generated by a
