Random Carbon Tax Policy and Investment Into Emission Abatement Technologies

open access: yesMathematical 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.

Dam Management in the Era of Climate Change

open access: yesMathematical 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 ...

Kinetic and Mean‐Field Modeling of Muscular Dystrophies

open access: yesStudies 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 ...

On the Numerical Solution of the Poisson Equation in the Smoothed Particle Hydrodynamics

open access: yesStudies in Applied Mathematics, Volume 157, Issue 4, October 2026.
ABSTRACT In the present work, we address some aspects related to the numerical solution of the Poisson equation within the framework of the Smoothed Particle Hydrodynamics (SPH). In this case, the Poisson equation is solved using nonlocal, kernel‐based discretizations of the differential operators (i.e., gradient, divergence, and Laplacian operators ...

On the geometry of WDVV equations and their Hamiltonian formalism in arbitrary dimension

open access: yesJournal of the London Mathematical Society, Volume 114, Issue 4, October 2026.
Abstract It is known that in low dimensions Witten–Dijkgraaf–Verlinde–Verlinde (WDVV) equations can be rewritten as commuting quasilinear bi‐Hamiltonian systems. We extend some of these results to arbitrary dimension N$N$ and arbitrary scalar product η$\eta$.
