6. Counting solutions to Diophantine equations
Sammanfattning : This thesis presents various results concerning the density of rational and integral points on algebraic varieties. These results are proven with methods from analytic number theory as well as algebraic geometry. LÄS MER
7. Combinatorics of solvable lattice models with a reflecting end
Sammanfattning : I den här avhandlingen studerar vi några exakt lösbara, kvantintegrerbara gittermodeller. Izergin bevisade en determinantformel för partitionsfunktionen till sexvertexmodellen på ett gitter av storlek n × n med Korepins domänväggrandvillkor (domain wall boundary conditions – DWBC).

8. Counting rational points on genus one curves
Sammanfattning : This thesis contains two papers dealing with counting problems for curves of genus one. We obtain uniform upper bounds for the number of rational points of bounded height on such curves. The main tools to study these problems are descent and various refined versions of Heath-Brown’s p-adic determinant method. LÄS MER
9. A comprehensive framework for the adoption of techno-relationship innovations : Empirical evidence from eCRM in manufacturing SMEs
Sammanfattning : Information Technology (IT) plays a significant role in today business competition. A prominent role is that it helps a firm to manage relationships with customers effectively. Adoption of appropriate technology can lead the firm to greater business competency, improve its business performance, and ensure it retains its competitive advantages. LÄS MER
10. The density of rational points and invariants of genus one curves
Sammanfattning : The present thesis contains three papers dealing with two arithmetic problems on curves of genus one, which are closely related to elliptic curves. The first problem is to study the density of rational points presented in Papers I and II. LÄS MER
