GMRES for the Differentiation Operator [PDF]

SIAM Journal on Numerical Analysis, 2009
We investigate using the gmres method with the differentiation operator. This operator is unbounded and thus does not fall into the framework of existing Krylov subspace theory. We establish conditions under which a function can be approximated by its own derivatives in a domain of the complex plane.

Composition-Differentiation Operator on Weighted Bergman Spaces

, 2023
In this paper, we study the complex symmetry of weighted composition-differentiation operator $D_{n, \psi, \phi}$ on weighted Bergman spaces $\mathcal{A}^2_{\alpha}$ with respect to the conjugation $C_{\mu, \eta}$ for $\mu, \eta \in \{z\in \mathbb{C}:|z|=

Weighted differentiation composition operators on the $Q_K(p,q)$ spaces and‎ their essential ‎norms‎ [PDF]

Journal of Mahani Mathematical Research
In this paper, firstly we obtain characterization for boundedness of the weighted differentiation composition operator  from $Q_K(p,q) $ space into weighted Zygmund space.

Chaos of the Differentiation Operator on Weighted Banach Spaces of Entire Functions [PDF]

, 2013
Motivated by recent work on the rate of growth of frequently hypercyclic entire functions due to Blasco, Grosse-Erdmann and Bonilla, we investigate conditions to ensure that the differentiation operator is chaotic or frequently hypercyclic on generalized

The Existence of a Global Attractor for one Fourth Order Hyperbolic Equation with Memory Operator

Universal Journal of Mathematics and Applications, 2019
In this work, the initial-boundary value problem for one fourth order semilinear hyperbolic equation with memory operator is considered (here the memory operator is under the operator of differentiation with respect to time variable).

SPECTRAL PROPERTIES OF SOME DIFFERENTIATION OPERATOR WITH DEVIATED ARGUMENT

, 2022
Differential equations with a deviating argument appeared in the literature as early as the 18th century in connection with the solution of the Euler problem of finding the general form of a line similar to its evolute.

Boolean Differential Operators

, 2012
We consider four combinatorial interpretations for the algebra of Boolean differential operators. We show that each interpretation yields an explicit matrix representation for Boolean differential operators.

Addendum to "Differential-Boundary Operators" [PDF]

Transactions of the American Mathematical Society, 1973
The proof of a lemma and the statement of another were omitted from an earlier paper. This corrects that omission.
