Bad Boundary Behavior in Star Invariant Subspaces II
We continue our study begun in [HR11] concerning the radial growth of functions in the model spaces (IH).
متن کاملSmooth Functions in Star-invariant Subspaces
In this note we summarize some necessary and sufficient conditions for subspaces invariant with respect to the backward shift to contain smooth functions. We also discuss smoothness of moduli of functions in such subspaces.
متن کاملWeak compactness in certain star-shift invariant subspaces
The context of much of the work in this paper is that of a backward-shift invariant subspace of the form KB :1⁄4 HðDÞ~BHðDÞ; where B is some infinite Blaschke product. We address (but do not fully answer) the question: For which B can one find a (convergent) sequence f fngn1⁄41 in KB such that the sequence of real measures flog j fnjdyg N n1⁄41 converges weak-star to some nontrivial singular me...
متن کاملBad boundary behavior in star invariant subspaces I
We discuss the boundary behavior of functions in star invariant subspaces (BH2)⊥, where B is a Blaschke product. Extending some results of Ahern and Clark, we are particularly interested in the growth rates of functions at points of the spectrum of B where B does not admit a derivative in the sense of Carathéodory.
متن کاملInvariant subspaces in Simpira
In this short note we report on invariant subspaces in Simpira in the case of four registers. In particular, we show that the whole input space (respectively output space) can be partitioned into invariant cosets of dimension 56 over F 28 . These invariant subspaces are found by exploiting the non-invariant subspace properties of AES together with the particular choice of Feistel configuration....
