Re: [FRIAM] Any non-biological complex systems?

In a simple Ising model example, the quadratic terms can be thought of as edges in an undirected graph. Depending on which J values are zero, there can one phase space or many independent phase spaces depending on how many disconnected components there are. A real material would be subject to

Yes, and systems can have subsystems. In my comment to Glen, my point was that a phase space is a description of a single system. -S ___ stephen.gue...@simtable.com CEO, Simtable http://www.simtable.com 1600 Lena St #D1, Santa

For what it’s worth, a linear space can have a subspace that is a linear space. Both the larger and smaller spaces are linear spaces. Of course “linear space” is much more precisely defined than “system”. Frank Frank C. Wimberly 140 Calle Ojo Feliz Santa Fe, NM 87505
