The oscillator's model with broken symmetry
Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2015 The equations of the oscillator motion are considered. The exact solutions are given in the form of exponents with an additional parameter that characterizes the asymmetry of the oscillations.

Hamiltonian Dynamics in the Theory of Abstraction [PDF]
, 2012 This paper deals with fluid flow dynamics which may be Hamiltonian in nature and yet chaotic.Here we deal with sympletic invariance, canonical transformations and stability of such Hamiltonian flows. As a collection of points move along, it carries along

Construction of discrete-time model for port-controlled Hamiltonian systems with applications [PDF]
, 2006 The issues of constructing a discrete-time model for Hamiltonian systems are in general different from those for dissipative systems. We propose an algorithm for constructing an approximate discrete-time model, which guarantees Hamiltonian conservation ...

Condensed Forms for Skew-Hamiltonian/Hamiltonian Pencils [PDF]
SIAM Journal on Matrix Analysis and Applications, 2000 Canonical forms and almost-Schur forms for a special class of pencils (real and complex skew-Hamiltonian / Hamiltonian) under \(J\)-congruences are considered in the paper. A necessary and sufficient condition for the existence of a \(J\)-Schur form is also given. The pencils studied occur for example in the theory of optimal control problems.

Hamiltonian Thermodynamics [PDF]
Nelineinaya Dinamika, 2020 It is believed that thermodynamic laws are associated with random processes occurring in the system and, therefore, deterministic mechanical systems cannot be described within the framework of the thermodynamic approach. In this paper, we show that thermodynamics (or, more precisely, a thermodynamically-like description) can be constructed even for ...

CoRR, 2015 Approximate Bayesian computation (ABC) is a powerful and elegant framework for performing inference in simulation-based models. However, due to the difficulty in scaling likelihood estimates, ABC remains useful for relatively low-dimensional problems. We introduce Hamiltonian ABC (HABC), a set of likelihood-free algorithms that apply recent advances in

Equivariant singularity theory with distinguished parameters: Two case studies of resonant Hamiltonian systems [PDF]
, 1998 We consider Hamiltonian systems near equilibrium that can be (formally) reduced to one degree of freedom. Spatio-temporal symmetries play a key role. The planar reduction is studied by equivariant singularity theory with distinguished parameters.

Hamiltonian purification [PDF]
Journal of Mathematical Physics, 2015 The problem of Hamiltonian purification introduced by Burgarth et al. [Nat. Commun. 5, 5173 (2014)] is formalized and discussed. Specifically, given a set of non-commuting Hamiltonians {h1, …, hm} operating on a d-dimensional quantum system ℋd, the problem consists in identifying a set of commuting Hamiltonians {H1, …, Hm} operating on a larger dE ...

Discrete exterior geometry approach to structure-preserving discretization of distributed-parameter port-Hamiltonian systems [PDF]
, 2011 This paper addresses the issue of structure-preserving discretization of open distributed-parameter systems with Hamiltonian dynamics. Employing the formalism of discrete exterior calculus, we introduce a simplicial Dirac structure as a discrete analogue
