We extend the analysis, initiated in arXiv:1901.01269, of thermodynamic stability four-dimensional asymptotically flat hairy black holes by considering a general class exact solutions Einstein-Maxwell-dilaton theory with non-trivial dilaton potential. find that, regardless values parameters theory, there always exists sub-class that are thermodynamically stable and have extremal limit well defi...

In this paper, we introduce a new hyperchaotic complex T-system. This system has complex nonlinear behavior which we study its dynamical properties including invariance, equilibria and their stability, Lyapunov exponents, bifurcation, chaotic behavior and chaotic attractors as well as necessary conditions for this system to generate chaos. We discuss the synchronization with certain and uncerta...
