In this note, we show that the main result (Theorem 3.2) due
to Asim et al. (Appl. Gen. Topol., 23(2), 363-376 (2022)
https://doi.org/10.4995/agt.2022.17418) is still valid if we remove the
assumption of continuity of ...

We explore the spatial spread of vector-borne infections with conditional vector preferences, meaning that vectors do not visit hosts at random. Vectors may be differentially attracted toward infected and uninfected hosts ...

In this paper, we consider some reaction–diffusion systems arising from two-component predator–prey models with various kinetics ranging from prey-dependent, ratio-dependent functional responses and subdiffusion. The goal ...

In this paper, we present a numerical method based on the fast Fourier transform
(FFT) to price call options on the minimum of two assets, otherwise known as
two-asset rainbow options. We consider two stochastic processes ...

A representation theorem is proved for De Morgan monoids that are (i) semilinear, i.e., subdirect products of totally ordered algebras, and (ii) negatively generated, i.e., generated by lower bounds of the neutral element. ...
We show that there exists a Banach space X which contains closed subspaces Y and Z with Y+Z=X such that the associated surjective summation operator Σ: Y×Z→X defined by Σ(y,z)= y+z for y∈Y and z∈Z has no Lipschitz right inverse.
In this study, we present theoretical considerations of, and analyse, the effects of circular geometry on the stability analysis of semi-linear parabolic PDEs of reaction–diffusion type with linear cross-diffusion for a ...

In this work, the solution of Riesz space fractional partial differential equations of parabolic type is considered. Since fractional-in-space operators have been applied to model anomalous diffusion or dispersion problems ...
Laboratory experiments as well as some field essays have revealed that the intracellular bacterium Wolbachia, deliberately introduced in Aedes spp female mosquitoes, drastically reduces their vector competence for dengue ...
This work presents a reaction–diffusion model that captures the spatio-temporal evolution of a bacterial colony and takes into account the quiescent stage. Using the theory of monotone wavefronts for cooperative and partially ...
The physiological structure of microbial communities in natural environments is typically a response to changes in internal and external conditions. External conditions may include the availability of nutrients, and the ...
We prove a version of the Ekeland Variational Principle (EkVP) in a weighted graph G and its equivalence to Caristi fixed point theorem and to the Takahashi minimization principle. The usual completeness and topological ...
Anguelov, Roumen; Lubuma, Jean M.-S.(Springer, 2023-09-22)
We present two results on the analysis of discrete dynamical systems and finite
difference discretizations of continuous dynamical systems, which preserve their
dynamics and essential properties. The first result provides ...
Generalizing MacPherson-Vilonen’s method [2] to arbitrary plane curve
singularities, we provide a classification of perverse sheaves on the neighborhood of the origin
in the complex plane, which are adapted to a germ of ...
Warrington, Miyako H.; Waterman, J.M. (Jane)(Oxford University Press, 2023-04)
The ecology, life histories, and physiology of many animals are changing in response to human-induced climate change. As the Earth warms, the ability of an animal to thermoregulate becomes ecologically and physiologically ...
