100 years of GAMM: Motivation, history and achievements

ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, Volume 106, Issue 1, January 2026.
Abstract The International Association of Applied Mathematics and Mechanics (Gesellschaft für Angewandte Mathematik und Mechanik, GAMM) was founded in 1923 with the goal to strengthen the field of scientific engineering by the foundation of an Engineering Association with strong scientific contacts to Applied Mathematics.

On the Locally Compact Hausdorff Property in the Analytical Solutions and Stability Analysis of the Caputo Fractional Belousov–Zhabotinsky System

Complexity, Volume 2026, Issue 1, 2026.
The fractional Belousov–Zhabotinsky system (BZS) is an important reaction–diffusion model used to describe oscillatory chemical reactions, pattern formation, and memory‐dependent dynamical processes arising in chemistry and related applied sciences. The main objective of this study is to investigate the analytical properties of the fractional BZS and ...

Neuronal Dynamics of an Intrinsically Bursting Neuron Through the Caputo–Fabrizio Fractal–Fractional Hodgkin–Huxley Model

International Journal of Differential Equations, Volume 2026, Issue 1, 2026.
This study introduces a novel fractal–fractional extension of the Hodgkin–Huxley model to capture complex neuronal dynamics, with particular focus on intrinsically bursting patterns. The key innovation lies in the simultaneous incorporation of Caputo–Fabrizio operators with fractional order α for memory effects and fractal dimension τ for temporal ...

Analysis of Bifurcation, Chaos, and Multiplicative White Noise Intensity of the Stochastic Fractional Nonlinear mCGL Model in an Optical Communication System

Journal of Function Spaces, Volume 2026, Issue 1, 2026.
This manuscript studies the stochastic time fraction modified complex Ginzburg–Landau (SFmCGL) model, an essential dynamical nonlinear model for describing the physical nature of how the optical wave soliton behaves and changes over time in a dynamic optical communication system.

Optimal Control of a Waterborne Disease Model With Dual Environmental Pathways and Hospitalization

Journal of Mathematics, Volume 2026, Issue 1, 2026.
Waterborne diseases remain a persistent public health crisis in low‐resource regions, where inadequate sanitation infrastructure, limited access to clean water, and weak healthcare systems create conditions for recurrent outbreaks. While mathematical models have advanced our understanding of disease transmission through water and direct contact, two ...

Some aspects of Leibniz algebra theory

, 2017
One of the key tendencies in the development of Leibniz algebra theory is the search for analogues of the basic results of Lie algebra theory. In this survey, we consider the reverse situation.

On the homological properties of the universal enveloping Leibniz algebra [PDF]

, 2018
We presente a study of graded Leibniz algebras and its universal enveloping Leibniz algebra. We prove that the universal enveloping Leibniz algebra of a finite dimensional graded Leibniz algebra is a quasi-Koszul algebra or an inhomogeneous Koszul ...

Exact Soliton Dynamics and Stability Analysis of a Fractional Order Coupled Wu‐Zhang System via a Generalized Riccati−Bernoulli−Bäcklund Approach

Journal of Mathematics, Volume 2026, Issue 1, 2026.
To investigate the fractional coupled Wu‐Zhang system analytically, this paper uses a hybrid generalized Riccati−Bernoulli sub‐ODE scheme and Bäcklund transformation to find the exact kink, antikink, and bright‐kink soliton solutions. The dynamical properties of these solutions are discussed using Hamiltonian formulation, phase‐portrait analysis, and ...

Boundary Algebra: A Simpler Approach to Boolean Algebra and the Sentential Connectives [PDF]

Boundary algebra [BA] is a algebra of type , and a simplified notation for Spencer-Brown’s (1969) primary algebra. The syntax of the primary arithmetic [PA] consists of two atoms, () and the blank page, concatenation, and enclosure between ‘(‘ and ...
