On Essential Fixed Points [PDF]
Wenn jede stetige Abbildung des kompakten Hausdorffschen Raumes \(X\) in sich wenigstens einen Fixpunkt hat, so ist \(p \in X\) wesentlicher Fixpunkt von \(f: X \rightarrow p\). [\glqq Wesentlich\grqq{} bedeutet: Zu jeder Umgebung \(U\) von \(p\) gibt es in \(X^X\) (kompakt-offen topologisiert) eine Umgebung \(N\) von \(f\), so daß jedes \(g \in N ...

Intuitionistic fixed point logic [PDF]
We study the system IFP of intuitionistic fixed point logic, an extension of intuitionistic first-order logic by strictly positive inductive and coinductive definitions. We define a realizability interpretation of IFP and use it to extract computational content from proofs about abstract structures specified by arbitrary classically true disjunction ...

Fractional order mathematical modeling of typhoid fever disease
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.

This article analyses two schemes: Mann-type and viscosity-type proximal point algorithms. Using these schemes, we establish Δ-convergence and strong convergence theorems for finding a common solution of monotone vector field inclusion problems, a ...

A fixed point algebra (FPA) is a pair \(\) of Boolean algebras satisfying the following properties: (1) Each \(\alpha \in B\) is a mapping from A into A; (2) Boolean operations in B are pointwise on A; (3) each constant mapping on A is an element of B; (4) each \(\alpha \in B\) has a fixed point in A.

On fixed points of permutations [PDF]
The number of fixed points of a random permutation of 1,2,...,n has a limiting Poisson distribution. We seek a generalization, looking at other actions of the symmetric group. Restricting attention to primitive actions, a complete classification of the limiting distributions is given.

Unique fixed points vs. least fixed points
AbstractThe aim of this paper is to compare two approaches to the semantics of programming languages: the least fixed point approach, and the unique fixed point approach. Briefly speaking, we investigate here the problem of existence of extensions of algebras with the unique fixed point property to ordered algebras with the least fixed point property ...
