Analysis of boundary layer MHD Darcy-Forchheimer radiative nanofluid flow with soret and dufour effects by means of marangoni convection

open access: yesCase Studies in Thermal Engineering, 2021
In the current article, the analysis of magnetohydrodynamic laminar flow past a vertical permeable surface is presented. The flow is considered in the existence of Dufour as well as Soret effects.

On local fixed or periodic point properties [PDF]

open access: yes, 2013
A space X has the local fixed point property LFPP, (local periodic point property LPPP) if it has an open basis $\mathcal{B}$ such that, for each $B\in \mathcal{B}$, the closure $\overline{B}$ has the fixed (periodic) point property.

Fixed Point Logics

open access: yesThe Bulletin of Symbolic Logic, 2002
AbstractWe consider fixed point logics, i.e., extensions of first order predicate logic with operators defining fixed points. A number of such operators, generalizing inductive definitions, have been studied in the context of finite model theory, including nondeterministic and alternating operators. We review results established in finite model theory,

A New Generalized Quasi-Newton Algorithm Based on Structured Diagonal Hessian Approximation for Solving Nonlinear Least-Squares Problems With Application to 3DOF Planar Robot Arm Manipulator

open access: yesIEEE Access, 2022
Many problems in science and engineering can be formulated as nonlinear least-squares (NLS) problems. Thus, the need for efficient algorithms to solve these problems can not be overemphasized.

Bounded Fixed Point Iteration

open access: yesDAIMI Report Series, 1991
In the context of abstract interpretation for languages without higher-order features we study the number of times a functional need to be unfolded in order to give the least fixed point. For the cases of total or monotone functions we obtain an exponential bound and in the case of strict and additive (or distributive) functions we obtain a quadratic ...

Fractional order mathematical modeling of typhoid fever disease

open access: yesResults in Physics, 2022
This manuscript is devoted to focusing on the modeling and numerical solution of the dynamical model of Typhoid Fever. We use the Atangana–Baleanu operator with the Mittag–Leffler function in Caputo sense to study the behavior of the model.

Conformal fixed point, Cosmological Constant and Quintessence [PDF]

open access: yes, 2002
We connect a possible solution for the ``cosmological constant problem'' to the existence of a (postulated) conformal fixed point in a fundamental theory.
