Abstract:
Let $\xi(t)$, $t\ge 0$, be a regenerating process; $B$ be a measurable set in the phase space; $x(t)$ be the indicator of the event $\{\xi(t)\in B\}$.
In this paper, a theorem is proved on convergence of $\displaystyle\frac{1}{T}\int_0^T x(t)\,dt$ to a final probability of the event $\{\xi(t)\in B\}$ as $T\to\infty$.
