Powers of the operator u(z)d/dz and their connection with some combinatorial numbers [PDF]
Notes on Number Theory and Discrete MathematicsIn this paper the operator A = u(z)d/dz is considered, where u is an entire or meromorphic function in the complex plane. The expansion of Aᵏ (k≥1) with the help of the powers of the differential operator D=d/dz is obtained, and it is shown that this ...

Operators Approximable by Hypercyclic Operators [PDF]
Mathematical Proceedings of the Royal Irish Academy, 2015 We show that operators on a separable infinite dimensional Banach space $X$ of the form $I +S$, where $S$ is an operator with dense generalised kernel, must lie in the norm closure of the hypercyclic operators on $X$, in fact in the closure of the mixing operators.

Singular integral operators, a brief historical overview of its evolution
Selecciones Matemáticas, 2022 In this work we give an analytical-historical view of the classical theory of singular integrals introduced by A.P. Calderón-A. Zygmund. Emphasis is given to their applications to PDEs and to some projections of the theory.
