Unilateral weighted shifts on
Konstantinos A. Beros, Paul B. Larson
Given a unilateral shift (determined by a bounded sequence ), a sequence is "hypercyclic" for iff the forward iterates of under are dense in $…
Maximal Tukey types, P-ideals and the weak Rudin-Keisler order
Konstantinos A. Beros, Paul B. Larson
In this paper, we study some new examples of ideals on with maximal Tukey type (that is, maximal among partial orders of size continuum). This discussion segues into an examina…
Canonical immunity and genericity
Achilles A. Beros, Konstantinos A. Beros
Whereas the usual notions of immunity -- e.g., immunity, hyperimmunity, etc. -- are associated with Cohen genericity, canonical immunity, as introduced by Beros, Khan and Kjos-Hans…
Homomorphism reductions on Polish groups
Konstantinos A. Beros
In an earlier paper, we introduced the following pre-order on the subgroups of a given Polish group: if is a Polish group and are subgroups, we say is {\e…
Index Sets of Universal Codes
Achilles A. Beros, Konstantinos A. Beros
We examine sets of codes such that certain properties are invariant under the choice of oracle from a range of possible oracles and establish a connection between such codes and Me…
Normal numbers and completeness results for difference sets
Konstantinos A. Beros
We consider some natural sets of real numbers arising in ergodic theory and show that they are, respectively, complete in the classes and $\mathcal D_…
