In this paper, we comment on the complexity of the invariant subspaces (under the bilateral Dirichlet shift f → ζ f) of the harmonic Dirichlet space D. Using the sampling theory of Seip and some work ...

A topological space X is pseudoradial if each of its non closed subsets A has a sequence (not necessarily with countable length) convergent to outside of A. We prove the following results concerning ...

Subspace codes are a class of error-correcting codes defined over the set of subspaces of a finite vector space. They have emerged as a powerful tool in network coding, where information is ...
