What mathematical conditions must be satisfied for a system to exhibit quasi-periodic forces leading to Strange Non-Chaotic Attractors (SNAs)? How do fractal dimensions of SNAs compare quantitatively to those of purely chaotic systems, and what implications does this have for their predictability? What specific experimental methods are used to distinguish SNAs from chaotic attractors in physical systems, particularly in dual-frequency oscillator setups?
