Abstract: We state precisely and demonstrate two conjectures of R.
Thomas following which a) the existence of a positive circuit in the oriented
interaction graph of a dioeerential system is a necessary condition for the existence
of several steady states, and b) the existence of a negative non-oriented
circuit of length at least two is a necessary condition for the existence of a
stable periodic orbit. (Update)
