Roessler system trajectory in 2D phase for xy, for xz, for yz, three non-linear ordinary differential equations defining chaotic dynamics in continuous time – similar to Lorenz’ chaos theory attractors but easier to analyze as two of its equations are linear: dx/dt = -y and dy/dt = x + ay. See eigenvalues, Poincare maps, bifurcation diagrams.
Terrific colors on these Ts.
The first day this design went public, a man in a Southern California post office line quipped, "I know half a dozen women who'd wear that today as representative of their daily lives!"
Soft, ribbed/fitted 100% cotton.
