Derivations on operator algebras
… as generators first introduces some basic semi-group theory (obtained from Pazy, A. [16), Section 1.1 and 1.2) after which the well-behavedness property is introduced in Section 3.2. Some general results mainly obtained from Sakai, S. [22), Section 3.2, is detailed. The proofs of Theorems …

Probabilistic Models on Fibre Bundles
… Parameter tuning can also be guided by a novel semi-group test arising from the geometric properties of diffusion kernel. For an example of real-world application, we use probabilistic models on fibre bundles to study evolutionary process on anatomical surfaces. In a separate chapter, we propose …

Nonhomogeneous Initial Boundary Value Problems for Two-Dimensional Nonlinear Schrodinger Equations
… mild solution) from the original equation by semi-group theory and then perform the Banach fixed-point argument. However, along the process, it is essential to select proper auxiliary function spaces and prepare all the corresponding norm estimates to complete the argument. In fact, the IBVP …

Cellular mappings on manifolds
… from a manifold onto itself is a topological semi-group and that the space of all cellular mappings of B<sup>n</sup> onto itself which are the identity on the boundary is locally contractible. The main theorem of Chapter two is that a mapping f of the n-sphere, n <strong>≠</strong> 4, onto …

Asymptotic Behaviour and Derivation of Mean Field Models
… equation, and show contraction of its semi-group in the Wasserstein distance when the spatial variable lies on the torus. Chapter 9 studies a more complex model of passive transport of a solute under a large and highly oscillatory fluid field. We prove a homogenisation result showing …

Coupled non-linear diffusion under periodic boundary conditions
… An alternative derivation of this result using semi-group theory is given. The complementary situation of an individual variable diffusing under non linear gradients is next addressed. Approximate, but applicable, series solutions may be formed. The non-linearity is accommodated within a stable …

Θεωρία προσέγγισης με νόρμες του Lorentz πάνω σε ομάδες του Lie
… on functions which are defined on nilpotent Lie groups. When the heat Kernel PT(N) is defined on a general nilpotent Lie group the estimate depends on the value of T i.e. is different for small and large T, hence the need to introduce the new Lorentz spaces which are development in this thesis. …

Primitive near-rings
… of some mathematicians that certain problems in group theory, particularly involving permutation groups and group representations, may perhaps be clarified by developing a coherent algebraic theory of near-rings. Moreover, there is an increasing recognition by mathematicians in many branches of …
