Analytical Approximant to a Quadratically Damped Forced Cubic-Quintic Duffing Oscillator

open access: yesThe Scientific World Journal, 2022
The cubic-quintic Duffing oscillator of a system with strong quadratic damping and forcing is considered. We give elementary approximate analytical solution to this oscillator in terms of exponential and trigonometric functions. We compare the analytical

Expansion in the distance parameter for two vortices close together [PDF]

open access: yes, 2000
Static vortices close together are studied for two different models in 2-dimen- sional Euclidean space. In a simple model for one complex field an expansion in the parameters describing the relative position of two vortices can be given in terms of ...

Certain results related to the N-transform of a certain class of functions and differential operators

open access: yesAdvances in Difference Equations, 2018
In this paper, we aim to investigate q-analogues of the natural transform on various elementary functions of special type. We obtain results associated with classes of q-convolution products, Heaviside functions, q-exponential functions, q-hyperbolic ...

Computing hypergeometric functions rigorously [PDF]

open access: yes, 2016
We present an efficient implementation of hypergeometric functions in arbitrary-precision interval arithmetic. The functions ${}_0F_1$, ${}_1F_1$, ${}_2F_1$ and ${}_2F_0$ (or the Kummer $U$-function) are supported for unrestricted complex parameters and ...

Exponential and trigonometric sums associated with the Lerch zeta and Legendre chi functions [PDF]

open access: yesComputers & Mathematics with Applications, 2010
It was shown that numerous (known and new) results involving various special functions, such as the Hurwitz and Lerch zeta functions and Legendre chi function, could be established in a simple, general and unified manner. In this way, among others, we recovered the Wang and Williams-Zhang generalizations of the classical Eisenstein summation formula ...
