Chebyshev cardinal functions for a new class of nonlinear optimal control problems generated by Atangana–Baleanu–Caputo variable-order fractional derivative

, 2020
This paper introduces a novel class of nonlinear optimal control problems generated by dynamical systems involved with variable-order fractional derivatives in the Atangana–Baleanu–Caputo sense.

On the consistency of cardinal direction constraints [PDF]

open access: yesArtificial Intelligence, 2005
We present a formal model for qualitative spatial reasoning with cardinal directions utilizing a co-ordinate system. Then, we study the problem of checking the consistency of a set of cardinal direction constraints.

Chebyshev cardinal wavelets for nonlinear stochastic differential equations driven with variable-order fractional Brownian motion

Chaos, Solitons & Fractals, 2019
This paper is concerned with a computational approach based on the Chebyshev cardinal wavelets for a novel class of nonlinear stochastic differential equations characterized by the presence of variable-order fractional Brownian motion. More precisely, in

Stationary Cardinals

Archive for Mathematical Logic, 1993
Let \(\kappa\) be an uncountable cardinal. A subset \(A\subseteq \kappa\) is said to be a 1-club set if \(A\) is stationary and every stationary reflection point belongs to \(A\). It is clear that this definition is a generalization of the definition of closed unbounded sets.

On the Cardinality of the Cardinal Virtues

International Journal of Philosophical Studies, 1999
This paper is a detailed study of what are traditionally called the cardinal virtues: prudence, justice, temperance and fortitude. I defend what I call the Cardinality Thesis, that the traditional four and no others are cardinal. I define cardinality in terms of three sub-theses, the first being that the cardinal virtues are jointly necessary for the ...

Cardinal Characteristics on Large Cardinals

2021
Das Studium von Kardinalzahlcharakteristiken auf regulären überabzählbaren Kardinalzahlen hat in den letzten zehn Jahren erheblich an Popularität gewonnen. Die Verallgemeinerungen des Cantor- und Baire-Raums auf reguläre überabzählbare Kardinalzahlen kappa induzieren auf natürliche Weise Verallgemeinerungen der zugehörigen Kardinalzahlcharakteristiken.
