Solvability of second order linear differential equations in the sequence space n(ϕ) $n(\phi)$

Advances in Difference Equations, 2018
We apply the concept of measure of noncompactness to study the existence of solution of second order differential equations with initial conditions in the sequence space n(ϕ) $n(\phi)$.

Expanding direction of the period doubling operator

, 1991
We prove that the period doubling operator has an expanding direction at the fixed point. We use the induced operator, a ``Perron-Frobenius type operator'', to study the linearization of the period doubling operator at its fixed point.

Jensen's Operator Inequality

, 2002
We establish what we consider to be the definitive versions of Jensen's operator inequality and Jensen's trace inequality for functions defined on an interval.

Operator space and operator system analogs of Kirchberg's nuclear embedding theorem

, 2015
The Gurarij operator space $\mathbb{NG}$ introduced by Oikhberg is the unique separable $1$-exact operator space that is approximately injective in the category of $1$-exact operator spaces and completely isometric linear maps.

Guidance on the assessment of exposure of operators, workers, residents and bystanders in risk assessment of plant protection products

EFSA Journal, 2022
This guidance is designed to assist risk assessors and applicants when quantifying potential non‐dietary, systemic exposures as part of regulatory risk assessment for plant protection products (PPPs). It is based on the Scientific Opinion on ‘Preparation

Morita embeddings for dual operator algebras and dual operator spaces

, 2017
We define a relation < for dual operator algebras. We say that B < A if there exists a projection p in A such that B and pAp are Morita equivalent in our sense.
