A mathematical paper by Inès Feki from the University of Sfax proposes new supplements to linear operator perturbation theory. The work involves a non-analytic perturbation with multiple parameters and applies the theory to a Gribov operator in Bargmann space.
Use Cases
- Studying spectral properties of non-selfadjoint operators based on the described perturbation framework.
- Applying multi-parameter perturbation techniques to problems in quantum field theory, as illustrated by the Gribov operator example.
- Developing theoretical foundations for perturbation methods in linear operator theory.
