A new chaotic hyperjerk system with four quadratic nonlinearities, its bifurcation analysis, multistability, circuit design and complete synchronization design via active backstepping control [PDF]

open access: yesArchives of Control Sciences
In this research work, we propose a new four-dimensional chaotic hyperjerk system with four quadratic nonlinearities. We carry out a detailed bifurcation analysis and derive conditions for the existence of a Hopf bifurcation for the new hyperjerk system.

On the Farrell–Tate K-theory of Out(Fn) $\operatorname {\mathrm {Out}}(F_n)$ upper O u t left parenthesis upper F Subscript n Baseline right parenthesis

open access: yesForum of Mathematics, Sigma
Using Lück’s Chern character isomorphism we obtain a general formula in terms of centralisers for the p-adic Farrell–Tate K-theory of any discrete group G with a finite classifying space for proper actions.

A new chaotic jerk system with a sinusoidal nonlinearity, its bifurcation analysis, multistability, circuit design and complete synchronization design via backstepping control [PDF]

open access: yesArchives of Control Sciences
In this research work, we investigate a new three-dimensional jerk system with three parameters in which one of the nonlinear terms is a sinusoidal nonlinearity.
