On the behavior of the solutions for certain neutral delay integro-differential equations [PDF]
E-Journal of Analysis and Applied MathematicsSome results are given on the behavior of solutions of scalar linear and constant coefficient neutral delay integro-differential equations. These results are obtained using two different real roots of the relevant characteristic equation.

Conservation Biology, Volume 40, Issue 5, October 2026.Abstract Ecological niche models (ENMs) are used to assess the abiotic preferences of species by linking their occurrences to the environmental conditions in which they live. We developed a fossil‐informed ENM framework that integrates mid‐Holocene and modern occurrences to test niche stability and reconstruct abiotic niche characteristics for four ...

Singular perturbations of integro-differential equations
Applied Mathematics and Computation, 2006 The paper deals with the integro-differential equation: \[ \epsilon^2 u_{\epsilon}''(t) + u_{\epsilon}'(t) = A u_{\epsilon}(t) + \int_0^t K(t-s)Au_{\epsilon}(s)ds + f_{\epsilon}(t),\;\;\; t\geq 0,\; \epsilon >0, \] in a Banach space, where \(A\) is the generator of a strongly continuous cosine family and \(K\) is a real-valued function.

Random Carbon Tax Policy and Investment Into Emission Abatement Technologies
Mathematical Finance, Volume 36, Issue 4, Page 804-825, October 2026.ABSTRACT We analyze the problem of a profit‐maximizing electricity producer, subject to carbon taxes, who decides on investments into CO2$\rm CO_2$ abatement technologies. We assume that the carbon tax policy is random and that the investment in the abatement technology is divisible, irreversible, and subject to transaction costs.

Electronic Journal of Differential Equations, 2015 In this work, we generalize so called Green's functional concept in literature to second-order linear integro-differential equation with nonlocal conditions. According to this technique, a linear completely nonhomogeneous nonlocal problem for a second-

Dam Management in the Era of Climate Change
Mathematical Finance, Volume 36, Issue 4, Page 870-895, October 2026.ABSTRACT Climate change has a dramatic impact, particularly by concentrating rainfall into a few short periods, interspersed with long dry spells. In this context, the role of dams is crucial. We consider the optimal control of a dam, where the water level must neither exceed a designated safety threshold nor fall below a minimum level to ensure ...

Predictive evolutionary genomics: principles, validation, and practice
New Phytologist, Volume 252, Issue 1, Page 36-48, October 2026.Summary Climate change and habitat loss are driving rapid evolutionary responses in populations world‐wide, which creates an urgent need for evolutionary forecasting in conservation and agriculture. Such forecasting can be categorized into three time scales: trait‐based models that use multivariate quantitative genetic equations to project correlated ...

Kinetic and Mean‐Field Modeling of Muscular Dystrophies
Studies in Applied Mathematics, Volume 157, Issue 4, October 2026.ABSTRACT We present a new class of models for assessing the cell dynamics characterizing muscular dystrophies. The proposed approach comprises a system of integro‐differential equations for the statistical distributions, over a large patient cohort, of the densities of muscle fibers and immune cells implicated in muscle inflammation, degeneration, and ...
