Perturbation Theory for Linear Operators

Perturbation Theory for Linear Operators

Perturbation theory for linear operators is a collection of diversified results in the spectral theory of linear operators, unified more or less loosely by their common concern with the behavior of spectral properties when the operators undergo a small change. Since its creation by RAY-LEIGH and SCHRODINGER, the theory has occupied an important place in applied mathematics; during the last ...

Perturbation theory of dynamical systems

Perturbation theory of dynamical systems

perturbation theory for a class of dynamical systems of dimension 3 and larger, including (but not limited to) integrable Hamiltonian systems. This will bring us, via averaging and Lie-Deprit series, all the way to KAM-theory. Finally, Chapter 4 contains an introduction to singular perturbation theory, which is concerned with systems that do not admit a well-defined limit when the ...

perturbation theory; Hilbert-space geometry near EPs 1. Introduction The Bender’s and Boettcher’s [1] idea of replacement of Hermiticity H = H † by parity-time symmetry (PT-symmetry) HPT= PTH of a Hamiltonian responsible for unitary evolution opened, after an appropriate mathematical completion [2–5] of the theory, a way towards the building of quantum models exhibiting non-Hermitian ...

TIME DEPENDENT PERTURBATION THEORY Figure 4.1: Time dependent perturbations typically exist for some time interval, here from t 0 to f. time when the perturbation is on we can use the eigenstates of H(0) to describe the system, since these eigenstates form a complete basis, but the time dependence is very nontrivial. Many physical questions can be couched in this language. For example, assume ...

Applications of Cosmological Perturbation Theory

Applications of Cosmological Perturbation Theory

perturbation theory, vorticity is sourced by a coupling term quadratic in energy density and entropy perturbations. This source term implies a qualitative di erence to linear order. Thus, while at linear order vorticity decays with the expansion of the universe, the same is not true at higher orders. This will have important implications on future measurements of the polarisation of the Cosmic ...

A survey on homological perturbation theory

A survey on homological perturbation theory

Homological perturbation theory (HPT), in a simple form rst isolated by Eilenberg and Mac Lane in the early 1950’s, is nowa-days a standard tool to handle algebraic incarnations of higher homotopies. A basic observation is that higher homotopy struc-tures behave much better relative to homotopy than strict struc- tures, and HPT enables one to exploit this observation in various concrete ...

Even the standard perturbation theory fits in this framework. The approach is based on carrying out an appropriate change of coordinates (or picture) in each case, and it can be formulated for any time-dependent linear system of ordinary differential equations. All of the procedures (except the standard perturbation theory) lead to approximate solutions preserving by construction unitarity ...

Boundary layer theory of forced magnetic reconnection due to an externally applied boundary perturbation is improved by introducing correct asymptotic matching which takes into account the effect of inertia in the inner layer precisely. The improved theory yields an integral equation for the time evolution of the reconnected flux.

Chern–Simons Perturbation Theory - arXiv

Chern–Simons perturbation theory on flat IR3 has been looked at previously by several groups of physicists. In [17], the theory up to 2-loops was found to be finite and to give knot invariants. In [7], [8], [12] a superspace formulation of the gauged fixed action was given. Two different arguments for finiteness to all orders are presented in [8] and [13], both assuming a nice ...
