Arbitrary systems are formed from elements, particles, or elementary objects. These elements enter any system and leave it. It is possible to formulate the notion of a lifetime or a first-passage time. When considering the finite size systems the finiteness of lifetime seems to be essential. From the random processes theory it follows that the existence and finiteness of a lifetime is provided by the existence of stationary states, physically meaning the existence of stationary structures. To describe the nonequilibrium states of a system we introduce a new thermodynamic parameter - the...
