S-and T-Invariants in Cyber Net Systems

Cyber nets are also known as self modifying nets. Though proposed anddefined some 20 years ago, they have never been under thorough study eversince. The reason for this is simple: the nonlinear nature of such nets keeps themaway from applications of well developed methods known to the whole Petri NetSociety in the world. This paper attempts to make a start of studying cybernets in depth by proposing a way to define and to verify S-invariants and T-invariants in such nets. These invariants reflect important …
