Generalized Volterra integral equations [PDF]

open access: yesCzechoslovak Mathematical Journal, 1982
This work develops the basic theory for the generalized Volterra equation \[ x(t)=f(t)+\int^{t}_{0}K(t,ds,x(s)),\quad 0\leq ...

Integrating Experimental Imaging and (Quantum‐Deformation)‐Curvature Dynamics in Bleb Morphogenesis

open access: yesEngineering Reports, Volume 8, Issue 4, April 2026.
We propose a (q,τ)$$ \left(q,\tau \right) $$‐fractional geometric flow model for cell blebbing that incorporates hereditary memory and viscoelastic effects in curvature‐driven membrane dynamics. Image‐based measurements of bleb geometry are coupled with fractional evolution equations and validated numerically.

Stability Issues for Selected Stochastic Evolutionary Problems: A Review

open access: yesAxioms, 2018
We review some recent contributions of the authors regarding the numerical approximation of stochastic problems, mostly based on stochastic differential equations modeling random damped oscillators and stochastic Volterra integral equations.

Application of High‐Order Direct Flux Reconstruction and Stiffness‐Resilient Time Integration to Simulations of Idealized Atmospheric Flows

open access: yesInternational Journal for Numerical Methods in Fluids, Volume 98, Issue 4, Page 448-468, April 2026.
The proposed work implements a direct flux reconstruction method for spatial discretization and a stiffness‐resilient exponential time integration method for temporal discretization on the cube‐sphere grid. A space‐time tensor formalism is employed to provide a general representation in any curvilinear coordinate system. This combination enables highly

New Explicit Bounds on Gamidov Type Integral Inequalities for Functions in Two Variables and Their Applications

open access: yesAbstract and Applied Analysis, 2014
Some linear and nonlinear Gamidov type integral inequalities in two variables are established, which can give the explicit bounds on the solutions to a class of Volterra-Fredholm integral equations.

Singularly perturbed volterra integral equations [PDF]

open access: yes, 1999
This thesis studies singularly perturbed Volterra integral equations of the form eu(t)=/(t,e)+fg(t,s,11(5)) ds, 00 is a small parameter The function f(t,e) is defined for 00. The aim is to find asymptotic approximations l to these solutions.

Seasonal variations in planktonic food web structure affect stability by shifting the distribution of energy fluxes

open access: yesOikos, Volume 2026, Issue 4, April 2026.
Seasonality in temperate ecosystems shapes species phenology, influencing interactions and food web structure. Variations in species richness and biomass affect trophic interaction strength, a crucial factor for community stability, which can be assessed through energy fluxes – an essential indicator of ecosystem function.

Mathematical Modelling and Intuition in Microbiology: A Perspective

open access: yesEnvironmental Microbiology, Volume 28, Issue 4, April 2026.
Mathematical modelling in microbiology converts verbal reasoning into internally consistent hypotheses that can provide testable predictions, infer hidden parameters, and generate transferable intuition. By selecting an appropriate level of description, researchers can connect data to explanatory principles.

Coexistence of Photosynthetic Marine Microorganisms, Viruses and Grazers: Towards Integration in Ocean Ecosystem Models

open access: yesEnvironmental Microbiology, Volume 28, Issue 4, April 2026.
Our study explores coexistence regimes of a virus and a zooplankton with a single phytoplankton for different model structures (left panel). The inclusion of an infected class and a resistant class is sufficient to generate coexistence regimes (middle panel). Using algebraic solutions, we optimise our model emphasising the importance of including viral

Solving Linear Volterra – Fredholm Integral Equation of the Second Type Using Linear Programming Method

open access: yesمجلة بغداد للعلوم, 2020
In this paper, a new technique is offered for solving three types of linear integral equations of the 2nd kind including Volterra-Fredholm integral equations (LVFIE) (as a general case), Volterra integral equations (LVIE) and Fredholm integral equations (
