ON THE PROPAGATION OF EQUATORIAL WAVES INTERACTING WITH A NON-UNIFORM CURRENT [PDF]

open access: yesOpen Communications in Nonlinear Mathematical Physics, 2022
We consider the propagation of equatorial waves of small amplitude, in a flow with an underlying non-uniform current. Without making the too restrictive rigid-lid approximation, by exploiting the available Hamiltonian structure of the problem, we derive ...

Further enumeration results concerning a recent equivalence of restricted inversion sequences [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2022
Let asc and desc denote respectively the statistics recording the number of ascents or descents in a sequence having non-negative integer entries.

Fractal Weyl Law for Open Chaotic Maps [PDF]

open access: yes, 2004
This contribution summarizes our work with M.Zworski on open quantum open chaoticmaps (math-ph/0505034). For a simple chaotic scattering system (the open quantum baker's map), we compute the "long-living resonances" in the semiclassical r\'{e}gime, and ...

Simple conditions for the transformation of dynamical coordinates into canonical ones in Hamiltonian dynamics [PDF]

open access: yesOpen Communications in Nonlinear Mathematical Physics
We obtain conditions, which when fulfilled, permit to transform the coordinates of a dynamical system into pairs of canonical ones for some Hamiltonian system.

Extracting dynamical equations from experimental data is NP-hard [PDF]

open access: yes, 2012
The behavior of any physical system is governed by its underlying dynamical equations. Much of physics is concerned with discovering these dynamical equations and understanding their consequences.

High order multiscale analysis of discrete integrable equations [PDF]

open access: yesOpen Communications in Nonlinear Mathematical Physics
In this article we present the results obtained applying the multiple scale expansion up to the order $\varepsilon^6$ to a dispersive multilinear class of equations on a square lattice depending on 13 parameters. We show that the integrability conditions

Quantization of the Riemann Zeta-Function and Cosmology [PDF]

open access: yes, 2007
Quantization of the Riemann zeta-function is proposed. We treat the Riemann zeta-function as a symbol of a pseudodifferential operator and study the corresponding classical and quantum field theories.

Area law for fixed points of rapidly mixing dissipative quantum systems [PDF]

open access: yes, 2015
We prove an area law with a logarithmic correction for the mutual information for fixed points of local dissipative quantum system satisfying a rapid mixing condition, under either of the following assumptions: the fixed point is pure, or the system is ...

Quantum collapse rules from the maximum relative entropy principle [PDF]

open access: yes, 2016
We show that the von Neumann--Lueders collapse rules in quantum mechanics always select the unique state that maximises the quantum relative entropy with respect to the premeasurement state, subject to the constraint that the postmeasurement state has to

A Way Out of the Quantum Trap [PDF]

open access: yes, 1998
We review Event Enhanced Quantum Theory (EEQT). In Section 1 we address the question "Is Quantum Theory the Last Word". In particular we respond to some of recent challenging staments of H.P. Stapp.
