Sammanfattning : The thesis consists of three parts, although each part belongs to a specific subject area in mathematics, they are considered as subfields of the perturbation theory. The main objective of the presented work is the study of the Dirac operator; the first part concerns the treatment of the spurious eigenvalues in the computation of the discrete spectrum. LÄS MER

Sammanfattning : We consider two main issues concerning the Dirac operator, the first is widelyknown as the appearance of spurious eigenvalues within the spectrum. The secondis the study of the asymptotic behavior of the eigenvalues for a family ofDirac operators with oscillatory potential added to the Coulomb-Dirac Hamiltonian. LÄS MER

Sammanfattning : In this thesis we present contributions related to texture detection and discrimination to be used for analyzing real world images. Many computer vision applications can benefit from a fast and low dimensional texture descriptor. LÄS MER
