WebTherefore we have straight-line trajectories in all directions. The motion is always inwards if the eigenvalue is negative (which means ), or outwards if the eigenvalue is positive (). This is called a singular node. It is an attractor if and unstable if . Here is the picture for the matrix , which has characteristic polynomial and eigenvalue . WebAbstract. Organisms are non-equilibrium, stationary systems self-organized via spontaneous symmetry breaking and undergoing metabolic cycles with broken detailed balance in the environment. The thermodynamic free-energy (FE) principle describes an organism’s homeostasis as the regulation of biochemical work constrained by the physical FE cost.
