Monsters in Hardy and Bergman spaces
(Taylor & Francis, 2002)A monster in the sense of Luh is a holomorphic function on a simply connected domain in the complex plane such that it and ...

Families of strongly annular functions: linear structure
(Springer, 2013-01)A function f holomorphic in the unit disk D is called strongly annular if there exists a sequence of concentric circles ...

Backward Φ-shifts and universality
(Elsevier, 2005-06-01)In this paper we consider spaces of sequences which are valued in a topological space E and study generalized backward ...

Interpolation by hypercyclic functions for differential operators
(Elsevier, 2009-04)We prove that, given a sequence of points in a complex domain Ω without accumulation points, there are functions having ...

Hypercyclic sequences of differential and antidifferential operators
(Elsevier, 1999-02)In this paper, we provide some extensions of earlier results about hypercyclicity of some operators on the Fréchet space ...

Universal transforms of the geometric series under generalized Riesz methods
(Springer, 2004-03)In this paper generalized Riesz methods (R, p, M) of summability are considered. We prove that, to each open set O ⊂ C ...

Linear subsets of nonlinear sets in topological vector spaces
(American Mathematical Society, 2014-01)For the last decade there has been a generalized trend in Mathematics on the search for large algebraic structures (linear ...

Linear Kierst-Szpilrajn theorems
(Polish Academy of Sciences, Institute of Mathematics, 2005)We prove in this paper the following result which extends in a somewhat ‘linear’ sense a theorem by Kierst and Szpilrajn ...

Dense linear manifolds of monsters
(Elsevier, 2002-12)In this paper the new concept of totally omnipresent operators is introduced. These operators act on the space of holomorphic ...

Sequences of differential operators: exponentials, hypercyclicity and equicontinuity
(Polish Academy of Sciences, Institute of Mathematics, 2001)In this paper, an eigenvalue criterion for hypercyclicity due to the first author is improved. As a consequence, some new ...

Existence and nonexistence of hypercyclic semigroups
(American Mathematical Society, 2007-03)In these notes we provide a new proof of the existence of a hypercyclic uniformly continuous semigroup of operators on any ...
