Non-Classical Symmetry Solutions to the Fitzhugh Nagumo Equation.
… non-classical method is utilized to find the <em>infinitesimal generator</em> and the <em>invariant surface condition</em> for the subgroup where the solutions for the desired PDE exist. Using the infinitesimal generator and the invariant surface condition, we reduce the PDE to a mildly nonlinear …

A semigroup/Laplace transform approach to approximating flows
… be strongly continuous and will have a linear, infinitesimal generator A. The purpose of this dissertation is to explore approximation methods for linear semigroups and/or Laplace transform inversion methods in order to reconstruct the flow starting with the linear generator A . In preparing for …

Asymptotic Problems Related to Smoluchowski-Kramers Approximation
… equations with diffusion governed by the infinitesimal generator of process \qu\ and \q\ and reaction term governed by a nonlinear function of KPP-type. In this case, the reaction-diffusion equation related to the process \qu\ is degenerate in terms of variable $(p,q)$. When the diffusion …

On the exact simulation of (skew) Brownian diffusions with discontinuous drift
… terms providing the semi-permeability) or by its infinitesimal generator as Markov process. In this thesis we first obtain a contour integral representation for the transition semigroup of the multiskew Brownian motion with constant drift, based on a fine analysis of its complex properties. Thanks …

Representable functionals and derivations on Banach quasi *-algebras
… conditions for a weak *-derivation to be the generator of such a group. An infinitesimal generator of a continuous one-parameter group of uniformly bounded weak *-automorphisms is shown to be closed and to have certain properties on its spectrum, whereas, to acquire such a group starting with …

A Dynamic Correlation Model for Pricing Credit Derivatives in A Lattice Framework
… for the bi-variate process. The joint generator is constructed on a two-dimensional lattice and a block-diagonalization algorithm is utilized during the computation. With the highly flexible choices of hazard structures, the proposed dynamic correlation model is capable of capturing …
