Generalized ρ-Almost Periodic Sequences and Applications

open access: yesFractal and Fractional, 2023
In this paper, we analyze the Bohr ρ-almost periodic type sequences and the generalized ρ-almost periodic type sequences of the form F:I×X→Y, where ∅≠I⊆Zn, X and Y are complex Banach spaces and ρ is a general binary relation on Y.

Rotation sets and almost periodic sequences [PDF]

open access: yesMathematische Zeitschrift, 2016
We study the rotational behaviour on minimal sets of torus homeomorphisms and show that the associated rotation sets can be any type of line segment as well as non-convex and even plane-separating continua.

Positive almost periodic type solutions to a class of nonlinear difference equation [PDF]

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2011
This paper is concerned with positive almost periodic type solutions to a class of nonlinear difference equation with delay. By using a fixed point theorem in partially ordered Banach spaces, we establish several theorems about the existence and ...

Tracking sea bed topography in the Jurassic. The Lotena Group in the Sierra de la Vaca Muerta (Neuquén Basin, Argentina) [PDF]

open access: yesGeologica Acta, 2005
The Lotena Group is a clastic to evaporitic unit up to 650 m thick that accumulated during the Middle to Late Jurassic in the Neuquén Basin, western Argentina.

Construction of almost periodic sequences with given properties

open access: yesElectronic Journal of Differential Equations, 2008
We define almost periodic sequences with values in a pseudometric space X and we modify the Bochner definition of almost periodicity so that it remains equivalent with the Bohr definition.

Non-almost periodic solutions of limit periodic and almost periodic homogeneous linear difference systems

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2015
We study limit periodic and almost periodic homogeneous linear difference systems. The coefficient matrices of the considered systems are taken from a given commutative group.

Analysis of two step nilsequences [PDF]

open access: yes, 2007
Nilsequences arose in the study of the multiple ergodic averages associated to Furstenberg's proof of Szemer\'edi's Theorem and have since played a role in problems in additive combinatorics. Nilsequences are a generalization of almost periodic sequences
