Kato's perturbation theorem and honesty theory
, 2015 We study an additive perturbation theorem for substochastic semigroups which is known as Kato's Theorem. There are two previously-known generalisations of Kato's Theorem, namely for abstract state spaces and for KB-spaces.

Spectral analysis of semigroups and growth-fragmentation equations [PDF]
, 2016 The aim of this paper is twofold: (1) On the one hand, the paper revisits the spectral analysis of semigroups in a general Banach space setting. It presents some new and more general versions, and provides comprehensible proofs, of classical results such

, 2006 In this book we define the new notion of neutrosophic rings. The motivation for this study is two-fold. Firstly, the classes of neutrosophic rings defined in this book are generalization of the two well-known classes of rings: group rings and semigroup ...

, 2012 In this thesis we consider in detail the following two fundamental problems for semigroup presentations: 1. Given a semigroup find a presentation defining it. 2. Given a presentation describe the semigroup defined by it.

Neighborhood Complexes and Generating Functions for Affine Semigroups [PDF]
Given a_{1}; a_{2},...a_{n} in Z^{d}, we examine the set, G, of all nonnegative integer combinations of these ai. In particular, we examine the generating function f(z) = Sum_{b in G}z^{b}.

Dynamical properties and structure of Julia sets of postcritically bounded polynomial semigroups
, 2011 We discuss the dynamic and structural properties of polynomial semigroups, a natural extension of iteration theory to random (walk) dynamics, where the semigroup G G of complex polynomials (under the operation of composition of ...

Affine Realizations for Levy Driven Interest Rate Models with Real-World Forward Rate Dynamics [PDF]
We investigate the existence of affine realizations for interest rate term structure models driven by Levy processes. Using as numeraire the growth optimal portfolio, we model the interest rate term structure under the real-world probability measure, and

KMS Dirichlet forms, coercivity and superbounded Markovian semigroups on von Neumann algebras
We introduce a construction of Dirichlet forms on von Neumann algebras M associated to any eigenvalue of the Araki modular Hamiltonian of a faithful normal non-tracial state, providing also conditions by which the associated Markovian semigroups are ...

Semigroups for One-Dimensional Schrödinger Operators with Multiplicative Gaussian Noise
, 2020 A problem of fundamental interest in mathematical physics is that of understanding the structure of the spectrum of random Schrödinger operators. An important tool in such investigations is the Feynman-Kac formula, which provides a simple probabilistic ...
