In this paper, some new three-dimensional
chaotic systems are proposed. The special property of these
autonomous systems is their identical eigenvalues. The systems
are designed based on the general form of quadratic jerk systems
with 10 terms, and some systems with stable equilibria. Using a
systematic computer search, 12 simple chaotic systems with
identical eigenvalues were found. We believe that systems with
identical eigenvalues are described here for the first time.
These simple systems are listed in this paper, and their
dynamical properties are investigated.
