1. On eigenvalues of the Schrödinger operator with a complex-valued polynomial potential
Sammanfattning : In this thesis, we generalize a recent result of A. Eremenko and A. Gabrielov on irreducibility of the spectral discriminant for the Schroedinger equation with quartic potentials. LÄS MER
2. Analysis of VSC-based HVDC systems
Sammanfattning : The main objective of this thesis is to perform stability and control studies in the area of VSC-HVDC systems. A major part of the investigation focuses on the development of procedures, whose aim is to understand, explain and avoid poorly-damped conditions or instability that may appear due to dc-side resonances, which stem from the interaction of converters and passive elements in such systems.

3. Spectral Asymptotics in Porous Media
Sammanfattning : .... LÄS MER
4. On nonlinear eigenvalue problems and critical point theory for indefinite functionals
Sammanfattning : .... LÄS MER
5. On the Analysis of DC Network Dynamics of VSC-based HVDC Systems
Sammanfattning : In this thesis, the dc network dynamics of VSC-HVDC systems is investigated through eigenvalue and frequency domain analysis. The eigenvalue analysis has been used to identify the factors that have an impact on the system stability. LÄS MER
