Scientific Machine Learning of Flow Resistance Using Universal Shallow Water Equations With Differentiable Programming

Water Resources Research, Volume 61, Issue 9, September 2025.
Abstract Shallow water equations (SWEs) are the backbone of most hydrodynamics models for flood prediction, river engineering, and many other water resources applications. The estimation of flow resistance, that is, the Manning's roughness coefficient n $n$, is crucial for ensuring model accuracy, and has been previously determined using empirical ...

Nonsymmetric Askey–Wilson Shift Operators

Studies in Applied Mathematics, Volume 155, Issue 3, September 2025.
ABSTRACT We classify the shift operators for the symmetric Askey–Wilson polynomials and construct shift operators for the nonsymmetric Askey–Wilson polynomials using two decompositions of nonsymmetric Askey–Wilson polynomials in terms of symmetric ones. These shift operators are difference–reflection operators, and we discuss the conditions under which

Isotopic lifting of Newtonian mechanics

Revista Técnica de la Facultad de Ingeniería, 2011
We present a simple isotopic generalization of the ordinary differential calculus, here called isodifferential calculus, which is based on an axiom-preserving generalization of the unit with compatible generalizations of fields, vector spaces and ...

On fixed‐point‐free involutions in actions of finite exceptional groups of Lie type

Journal of the London Mathematical Society, Volume 112, Issue 3, September 2025.
Abstract Let G$G$ be a nontrivial transitive permutation group on a finite set Ω$\Omega$. By a classical theorem of Jordan, G$G$ contains a derangement, which is an element with no fixed points on Ω$\Omega$. Given a prime divisor r$r$ of |Ω|$|\Omega |$, we say that G$G$ is r$r$‐elusive if it does not contain a derangement of order r$r$. In a paper from

Functorial constructions related to double Poisson vertex algebras

Journal of the London Mathematical Society, Volume 112, Issue 3, September 2025.
Abstract For any double Poisson algebra, we produce a double Poisson vertex algebra using the jet algebra construction. We show that this construction is compatible with the representation functor which associates to any double Poisson (vertex) algebra and any positive integer a Poisson (vertex) algebra.
