26. Trace Formulae for Fourth Order Differential Operators and their Applications
Sammanfattning : Paper I. Trace Formulae and Spectral Properties of FourthOrder Differential Operators.We derive trace formulae forfourth order differential operators in dimension one anddiscuss their connection with sharp Lieb-Thirring inequalitiesfor the Riesz means of negative eigenvalues of order γ≥ 7/4.

27. Secrecy in Cognitive Radio Networks
Sammanfattning : With the considerable growth of wireless networks in recent years, the issue of network security has taken an important role in the design of communication devices and protocols. Indeed, due to the broadcast nature of these networks, communications can potentially be attacked by malicious parties, and therefore, the protection of transmitted data has become a main concern in today's communications.

28. Guaranteeing Generalization via Measures of Information
Sammanfattning : During the past decade, machine learning techniques have achieved impressive results in a number of domains. Many of the success stories have made use of deep neural networks, a class of functions that boasts high complexity. Classical results that mathematically guarantee that a learning algorithm generalizes, i.e. LÄS MER
29. Target zones : theory and evidence
Sammanfattning : In three papers we analyze the effects on different economic variables of implementing explicit target zones for economic policy. The first paper examines and tests two different models for devaluations in a target zone. LÄS MER
30. Holomorphic embeddings and applications
Sammanfattning : In the first part of this thesis we consider the question of the number of equivalenceclasses of holomorphic embeddings of Ck into Cn. We show the existence of holomorphicfamilies of proper holomorphic embeddings of Ck into Cn (0 < k < n−1),such that members of the family are pairwise nonequivalent in a suitable sense. LÄS MER
