Abstract:
With a view to the more ultimate goal of providing fresh perspectives to address the perennial theological problem of the compatibility of divine sovereignty and human freedom, this thesis undertakes a critically constructive re-examination of fundamental orientations guiding Wolfhart Pannenberg’s thought, arguing that, when properly read through the far-reaching and decisive influences of Duns Scotus and Friedrich Schelling, influences hitherto only scantily acknowledged, Pannenberg’s overarching theology, from very early in his career to his latest writings, must be understood throughout as

Abstract:
The subject of this thesis in the study of nite extensions of p-adic fields, in different aspects. Via the study of the Galois module of p-th power classes L =(L )p of a general Galois extension L=K of degree p, it is possible to deduce and classify the extensions of degree p2 of a p-adic field. We exhibit formulae counting how many times a certain group appears as Galois group of the normal closure, generalizing previous results. In general degree we give a synthetic formula counting isomorphism classes of extensions of fixed degree. The formula is obtained via Krasner formula and a

Abstract:
For K a cubic field with only one real embedding and α, β ϵ K, we show how to construct an increasing sequence {m_n} of positive integers and a subsequence {ψ_n} such that (for some constructible constants γ₁, γ₂ > 0): max{ǁm_nαǁ,ǁm_nβǁ} < [(γ₁)/(m_n^(¹/²))] and ǁψ_nαǁ < γ₂/[ψ_n^(¹/²) log ψ_n] for all n. As a consequence, we have ψ_nǁψ_nαǁǁψ_nβǁ < [(γ₁ γ₂)/(log ψ_n)] for all n, thus giving an effective proof of Littlewood's conjecture for the pair (α, β). Our proofs are elementary and use only standard results from algebraic number theory and the theory of continued fractions.

Abstract:
In this thesis we study Ax-Schanuel type inequalities for abstract differential equations. A motivating example is the exponential differential equation. The Ax-Schanuel theorem states positivity of a predimension defined on its solutions. The notion of a predimension was introduced by Hrushovski in his work from the 1990s where he uses an amalgamation-with-predimension technique to refute Zilber's Trichotomy Conjecture. In the differential setting one can carry out a similar construction with the predimension given by Ax-Schanuel. In this way one constructs a limit structure whose theory turn

Abstract:
In Part I, we investigate the principal series representations of the n-fold covering groups of the special linear group over a p-adic field. Such representations are constructed via the Stone-von Neumann theorem. We have three interrelated results. We first compute the K-types of these representations. We then give a complete set of reducibility points for the unramified principal series representations. Among these are the unitary unramified principal series representations, for which we further investigate the distribution of the K-types among its irreducible components. In Part II, we
