Solutions for the General, Confluent and Biconfluent Heun equations and their connection with Abel equations

, 2004
In a recent paper, the canonical forms of a new multi-parameter class of Abel differential equations, so-called AIR, all of whose members can be mapped into Riccati equations, were shown to be related to the differential equations for the hypergeometric ...

Early clinical pharmacology evaluation of the novel anti‐inflammatory macrolide, glasmacinal (EP395): tolerability, pharmacokinetics and drug interactions

British Journal of Clinical Pharmacology, EarlyView.
Abstract Aims This work assessed the pharmacokinetics (PK), safety and tolerability of glasmacinal (EP395, an oral anti‐inflammatory macrolide with negligible antimicrobial activity in development for COPD treatment) in two healthy participant trials: ‘first‐in‐human’ (FIH) and ‘drug–drug‐interaction’ (DDI).

Explicit algebraic solution of Zolotarev's First Problem for low-degree polynomials

Journal of Numerical Analysis and Approximation Theory, 2019
E.I. Zolotarev's classical so-called First Problem (ZFP), which was posed to him by P.L. Chebyshev, is to determine, for a given \(n\in{\mathbb N}\backslash\{1\}\) and for a given \(s\in{\mathbb R}\backslash\{0\}\), the monic polynomial solution \(Z ...

Induced Photoelectron Circular Dichroism as a Probe for Distinguishing Diastereotopic Lone Electron Pairs. [PDF]

Angew Chem Int Ed Engl
Gas‐phase complexation of chiral methyloxirane by achiral phenol results in induced chiroptical response of phenol. Two pseudo enantiomer complexes are observed, corresponding to hydrogen bonding from phenol to either of the lone electron pair of the methyloxirane oxygen, denoted as Pro R and Pro S, with opposite chiral deformation of phenol and ...

Rational solutions and limit cycles of polynomial and trigonometric Abel equations

Electronic Journal of Qualitative Theory of Differential Equations
e study the Abel differential equation $x'=A(t)x^3+B(t)x^2+C(t)x$. Specifically, we find bounds on the number of its rational solutions when $A(t), B(t)$ and $C(t)$ are polynomials with real or complex coefficients; and on the number of rational limit ...

Higher-order Abel equations: Lagrangian formalism, first integrals and Darboux polynomials

, 2009
A geometric approach is used to study a family of higher-order nonlinear Abel equations. The inverse problem of the Lagrangian dynamics is studied in the particular case of the second-order Abel equation and the existence of two alternative Lagrangian ...

Algebraic geometry of the center-focus problem for Abel differential equations [PDF]

Ergodic Theory and Dynamical Systems, 2014
The Abel differential equation $y^{\prime }=p(x)y^{3}+q(x)y^{2}$ with polynomial coefficients $p,q$ is said to have a center on $[a,b]$ if all its solutions, with the initial value $y(a)$ small enough, satisfy the condition $y(a)=y(b)$. The problem of giving conditions on $(p,q,a,b)$ implying a center for the Abel equation is analogous to the classical

A Decision‐Making Model for Implementing Green Technology in Sustainable Building Projects

Business Strategy and the Environment, EarlyView.
ABSTRACT Green technology (GT) adoption is pivotal for reconciling environmental stewardship with economic viability in the built environment, particularly in resource‐constrained emerging economies. However, empirical evidence on how specific GT drivers actively mitigate adoption barriers remains scarce.

General Solutions of the Abel Differential Equations

, 2020
The Abel differential equations play a significant role in various fields of mathematics and applied sciences and are classified into two types: the first kind and the second kind. A novel derivative condition for the general solution of first-kind Abel equation is introduced.

Integrable dissipative nonlinear second order differential equations via factorizations and Abel equations [PDF]

Physics Letters A, 2013
We emphasize two connections, one well known and another less known, between the dissipative nonlinear second order differential equations and the Abel equations which in its first kind form have only cubic and quadratic terms. Then, employing an old integrability criterion due to Chiellini, we introduce the corresponding integrable dissipative ...
