Discrete Hamiltonians of discrete Painlevé equations [PDF]

open access: yesAnnales de la Faculté des sciences de Toulouse : Mathématiques, 2021
We express discrete Painlevé equations as discrete Hamiltonian systems. The discrete Hamiltonian systems here mean the canonical transformations defined by generating functions. Our construction relies on the classification of the discrete Painlevé equations based on the surface-type. The discrete Hamiltonians we obtain are written in the logarithm and

Discrete gravity [PDF]

open access: yesJournal of High Energy Physics, 2021
Abstract We assume that the points in volumes smaller than an elementary volume (which may have a Planck size) are indistinguishable in any physical experiment. This naturally leads to a picture of a discrete space with a finite number of degrees of freedom per elementary volume.

Discrete Polymatroids [PDF]

open access: yesJournal of Algebraic Combinatorics, 2002
The discrete polymatroid is a multiset analogue of the matroid. This paper studies the combinatorics and the algebra on discrete polymatroids. An algebraic aspect of this paper is to study Ehrhart rings and base rings together with toric ideals of discrete polymatroids. One result on toric ideals of discrete polymatroids given in this paper is Theorem.

Taylor series expansion in discrete Clifford analysis [PDF]

open access: yes, 2013
Discrete Clifford analysis is a discrete higher-dimensional function theory which corresponds simultaneously to a refinement of discrete harmonic analysis and to a discrete counterpart of Euclidean Clifford analysis.

Using discrete-time hyperchaotic-based asymmetric encryption and decryption keys for secure signal transmission [PDF]

open access: yes, 2014
In this paper, a framework for the synchronization of two non-identical discrete-time hyperchaotic systems, namely the 3D Baier-Klein and the 3D Hitzel-Zele maps, based on the use of hybrid output feedback concept and aggregation techniques, is employed ...

Discrete Hamiltonian Variational Integrators [PDF]

open access: yes, 2010
We consider the continuous and discrete-time Hamilton's variational principle on phase space, and characterize the exact discrete Hamiltonian which provides an exact correspondence between discrete and continuous Hamiltonian mechanics.
