On the Topological Entropy of Nonautonomous Differential Equations
Journal of Applied Mathematics and Physics, 2019 The purpose of this paper is to extend the concept topological entropy to nonautonomous linear systems. Next, we shall give estimation of the topological entropy for the class of bounded linear equations on Rn. Finally, we are about to investigate the invariant properties of one through the transformations such as topological conjugacy ...

Smart Cities, Urban Transportation and Air Quality: A Decade of Literature on Italian Largest Cities
Journal of Economic Surveys, EarlyView.ABSTRACT Traffic congestion and its associated negative impacts on economic performance and environmental sustainability, particularly air quality, have long plagued urban centers. This article reviews the technologies and policies adopted by major Italian cities to address these issues, focusing on interventions from 2014 to 2024. Through a keyword co‐

International Transactions in Operational Research, Volume 34, Issue 1, Page 460-500, January 2027.Abstract The application of automated ground vehicles (AGVs) is well‐established in closed environments such as port terminals, while their operation in open areas remains challenging. In this work, we set out to overcome this limitation by introducing platooning as a transfer mode in heterogeneous vehicle networks.

Sundman‐Like Transformations and the NRT Nonlinear Schrödinger Equation
Mathematical Methods in the Applied Sciences, Volume 49, Issue 13, Page 14791-14810, 15 September 2026.ABSTRACT We present a new generalization of the well‐known power‐type Sundman transformation, involving not only powers of the function but also of its derivative, along with its inverse. Our aim is to explore the use of such transformations in the derivation of solutions of ordinary differential equations and in the study of their properties.

The Legacy of Policy Inaction in Climate‐Growth Models
International Economic Review, Volume 67, Issue 3, Page 915-935, August 2026.ABSTRACT To better understand the structure and core mechanisms of a broad class of climate‐growth models, we study a simplified version of the dynamic integrated model of climate and the economy (DICE) through the lens of growth theory. We analytically show that this model features a continuum of saddle‐point stable steady states.

On the Dynamic of a Nonautonomous [PDF]
Journal of Sciences, Islamic Republic of Iran, 2009 Nonlinear difference equations of higher order are important in applications; such equations appear naturally as discrete analogues of differential and delay differential equations which model various diverse phenomena in biology, ecology, economics ...

On the linearization theorem for nonautonomous differential equations
Bulletin des Sciences Mathématiques, 2015 In [J. Math. Anal. Appl. 41, 753--758 (1973; Zbl 0272.34056)], \textit{K. J. Palmer} proposed some generalization of the Hartman and Grobman's linearization theorem [\textit{P. Hartman}, Ordinary differential equations. York-London-Sydney: John Wiley and Sons, Inc (1964; Zbl 0125.32102)] to the nonautonomous case. Here, the authors consider the system \

The Structure of Vertebrate Antigen Receptor Repertoires: An Evolutionary Perspective
Immunological Reviews, Volume 341, Issue 1, August 2026.ABSTRACT In vertebrate adaptive immune systems, somatically diversified antigen receptors assume a central role in self/nonself discrimination. Attesting to the presence of a unique but unknown selective environment at early stages of vertebrate evolution, this facility emerged twice, in the ancestors of jawless and jawed vertebrates.
