Disjoint hypercyclicity equals disjoint supercyclicity for families of Taylor-type operators
Open Mathematics, 2018 We characterize disjointness of supercyclic operators which map a holomorphic function to a partial sum of the Taylor expansion. In particular, we show that disjoint hypercyclicity equals disjoint supercyclicity for families of Taylor-type operators ...

Extended Cesáro operators between generalized Besov spaces and Bloch type spaces in the unit ball
Journal of Function Spaces, Volume 7, Issue 3, Page 209-223, 2009., 2009 Let 𝑔 be a holomorphic of the unit ball B in the n‐dimensional complex space, and denote by Tg the extended Cesáro operator with symbol g. Let 0 < p < +∞, −n − 1 < q < +∞, q > −1 and α > 0, starting with a brief introduction to well known results about Cesáro operator, we investigate the boundedness and compactness of Tg between generalized Besov space

Essential norm of integral operators on Morrey type spaces
, 2016 In this paper, we investigate the essential norm of two classes of integral operators on Morrey type spaces H2 K . As an application, we characterize the compactness of these operators. Mathematics subject classification (2010): 30H25, 47B38.

The essential norm of a composition operator mapping into Qk type spaces
Journal of Function Spaces, Volume 6, Issue 3, Page 241-258, 2008., 2008 An asymptotic formula for the essential norm of the composition operator Cφ(f) : = f∘φ, induced by an analytic self‐map φ of the unit disc, mapping from the α‐Bloch space ℬα or the Dirichlet type space Dαp into Qk(p, q) is established in terms of an integral condition.

Bloch‐type space of temperature functions on a finite cylinder
Journal of Function Spaces, Volume 5, Issue 3, Page 287-297, 2007., 2007 We define the Bloch‐type space BT as the linear space of temperature functions on the cylinder ST=S1×(0,T) such that sup(x,t)∈Tt| ∂u∂t(x,t) |<∞, ΩT = [0,2] × (0, T); we prove that (b1(ST))*=BT, where b1(ST) is the Bergman space of temperature functions on ST belonging to L1(ΩT, dxdt).

The maximal operator in weighted variable spaces Lp(⋅)
Journal of Function Spaces, Volume 5, Issue 3, Page 299-317, 2007., 2007 We study the boundedness of the maximal operator in the weighted spaces Lp(⋅)(ρ) over a bounded open set Ω in the Euclidean space ℝn or a Carleson curve Γ in a complex plane. The weight function may belong to a certain version of a general Muckenhoupt‐type condition, which is narrower than the expected Muckenhoupt condition for variable exponent, but ...

New proof of Nagnibida′s theorem
Journal of Function Spaces, Volume 4, Issue 1, Page 85-90, 2006., 2006 Using the Duhamel product for holomorphic functions we give a new proof of Nagnibida’s theorem on unicellularity of integration operator Ja,(Jaf)(z)=?azf(t)dt, acting in the space Hol(O).

Chaotic operators on hypergroups
, 2018 In this paper, we initiate a study of chaos, in the sense of Devaney, and topological transitivity on the Lp space of hypergroups, and give some sufficient and necessary conditions for weighted translation operators on hypergroups to be chaotic and ...
