On tau functions associated with linear systems [PDF]
, 2012 \noindent {\bf Abstract} This paper considers the Fredholm determinant $\det (I-\Gamma_x)$ of a Hankel integral operator on $L^2(0, \infty )$ with kernel $\phi (s+t+2x)$, where $\phi$ is a matrix scattering function.

Hamiltonian and Variational Linear Distributed Systems [PDF]
, 2002 We use the formalism of bilinear- and quadratic differential forms in order to study Hamiltonian and variational linear distributed systems. It was shown in [1] that a system described by ordinary linear constant-coefficient differential equations is ...

Hypocoercivity and hypocontractivity concepts for linear dynamical systems
, 2023 For linear dynamical systems (in continuous-time and discrete-time), we revisit and extend the concepts of hypocoercivity and hypocontractivity and give a detailed analysis of the relations of these concepts to (asymptotic) stability, as well as (semi ...

An online intelligent robust adaptive LSQR estimation method for LTI state space model
IET Control Theory & Applications, 2023 Regarding the low accuracy and instability of common online methods for estimating dynamic models in the time domain, in the presence of uncertainty in system dynamics, sensor noise and environmental disturbances, this area is still open for further ...

On Linear Information Systems [PDF]
Electronic Proceedings in Theoretical Computer Science, 2010 Scott's information systems provide a categorically equivalent, intensional description of Scott domains and continuous functions. Following a well established pattern in denotational semantics, we define a linear version of information systems, providing a model of intuitionistic linear logic (a new-Seely category), with a "set-theoretic ...

Many-Body Systems and Quantum Chaos: The Multiparticle Quantum Arnol’d Cat
Condensed Matter, 2019 A multi-particle extension of the Arnol’d cat Hamiltonian system is presented, which can serve as a fully dynamical model of decoherence. The behavior of the von Neumann entropy of the reduced density matrix is studied, in time and as a function of the ...

A new method for solving ill-conditioned linear systems [PDF]
Opuscula Mathematica, 2013 An accurate numerical method is established for matrix inversion. It is shown theoretically that the scheme possesses the high order of convergence of seven. Subsequently, the method is taken into account for solving linear systems of equations.

Particle scale force sensor based on intensity gradient method in granular photoelastic experiments
New Journal of Physics, 2019 The intensity gradient method ( G ^2 method), namely computing the light intensity gradient-squared, is a widely used non-invasive experimental method to extract stress information from quasi-two-dimensional photoelastic granular materials.

Equilibrium controllability analysis and input design of linear systems
SICE Journal of Control, Measurement, and System Integration, 2023 In setpoint control, an equilibrium of the system to be controlled is typically employed as the setpoint. Thus, it is important to know the “possible equilibria” of the system, i.e.
