Classical Chaos in a Driven One-Dimensional Quartic Anharmonic Oscillator

open access: yesComputation
In this work, we investigate the transition from regular dynamics to chaotic behavior in a one-dimensional quartic anharmonic classical oscillator driven by a time-dependent external square-wave force.

Quartic Regularity. [PDF]

open access: yesVietnam J Math
In this paper, we propose new linearly convergent second-order methods for minimizing convex quartic polynomials. This framework is applied for designing optimization schemes, which can solve general convex problems satisfying a new condition of quartic ...

Global bifurcation analysis of a rational Holling system [PDF]

open access: yesКомпьютерные исследования и моделирование, 2017
In this paper, we consider a quartic family of planar vector fields corresponding to a rational Holling system which models the dynamics of the populations of predators and their prey in a given ecological or biomedical system and which is a variation on

Moments of central values of quartic Dirichlet L-functions [PDF]

open access: yesJournal of Number Theory, 2021
In this paper, we study moments of the central values of quartic Dirichlet $L$-functions and establish quantitative non-vanishing result for these $L$-values.

Inverse Numerical Range and Determinantal Quartic Curves

open access: yesMathematics, 2020
A hyperbolic ternary form, according to the Helton–Vinnikov theorem, admits a determinantal representation of a linear symmetric matrix pencil. A kernel vector function of the linear symmetric matrix pencil is a solution to the inverse numerical range ...
