THE FINITE SECTION METHOD FOR DISSIPATIVE OPERATORS [PDF]
Summary: We show that for self-adjoint Jacobi matrices and Schrödinger operators, perturbed by dissipative potentials in \(\ell^1 (\mathbb N)\) and \(L^1(0,\infty )\), respectively, the finite section method does not omit any points of the spectrum. In the Schrödinger case, two different approaches are presented.

Exponential stabilty for a Timoshenko system with nonlocal delay
The purpose of this paper is to study the Timoshenko system with nonlocal time-delayed condition. The well-posedness is proved by Hille-Yosida theorem.

We study the dynamical invariant for dissipative three coupled oscillators mainly from the quantum mechanical point of view. It is known that there are many advantages of the invariant quantity in elucidating mechanical properties of the system.

The limit behavior of trajectories of dissipative quadratic stochastic operators on a finite-dimensional simplex is fully studied. It is shown that any dissipative quadratic stochastic operator has either unique or infinitely many fixed points.

Theory of quantum fluctuations of optical dissipative structures and its application to the squeezing properties of bright cavity solitons [PDF]
We present a method for the study of quantum fluctuations of dissipative structures forming in nonlinear optical cavities, which we illustrate in the case of a degenerate, type I optical parametric oscillator.

Dissipation-induced enhancement of quantum fluctuations
We study a quantum harmonic oscillator linearly coupled through the position operator $\hat{q}$ to a first bath and through the momentum operator $\hat{p}$ to a second bath yielding an Ohmic–Drude dissipation.

Dimension estimates of the attractor for the dissipative quantum Zakharov equations
The finite dimension estimates of Hausdorff dimension and fractal dimension of the attractor of the dissipative quantum Zakharov equations are mainly studied by using the estimates of the Lyapunov exponents. The main results on the attractor are obtained

Operator splitting for dissipative delay equations
We investigate Lie-Trotter product formulae for abstract nonlinear evolution equations with delay. Using results from the theory of nonlinear contraction semigroups in Hilbert spaces, we explain the convergence of the splitting procedure.

Variational principle for theories with dissipation from analytic continuation
The analytic continuation from the Euclidean domain to real space of the one-particle irreducible quantum effective action is discussed in the context of generalized local equilibrium states.
