1. On Integral Representation with Weights on Complex Manifolds
Sammanfattning : .... LÄS MER
2. Retrieval of equivalent currents by the use of an integral representation and the extinction theorem --- radome applications
Sammanfattning : The aim of this thesis is to solve an inverse source problem. The approach is based on an integral representation together with the extinction theorem. Both a scalar and a full-wave integral representation are implemented and solved by a Method of Moment procedure. LÄS MER
3. Integral representations of Herglotz-Nevanlinna functions
Sammanfattning : In this thesis, we study integral representations of Herglotz-Nevanlinna functions, that is to say holomorphic functions defined on a product of several copies of the complex upper half-plane having non-negative imaginary part. The manuscript is divided into three parts, beginning with a general introduction followed by two papers. LÄS MER
4. The one-dimensional Kondo Lattice in the Majorana Fermion representation
Sammanfattning : This thesis analyses the possibilities offered by the representation of quantum mechanical operators in terms of Majorana fermions. These objects can be imagined as algebraic constituents of the fermionic degrees of freedom, allowing for a different representation of many Hamiltonians. LÄS MER
5. Toric varieties and residues
Sammanfattning : The multidimensional residue theory as well as the theory of integral representations for holomorphic functions is a very powerful tool in complex analysis. The computation of integrals, solving algebraic or differential equations is usually reduced to some residue integral. LÄS MER
