Informal: Specific Topic System, Initial Components $\Gamma_{i_0}$. For the fixed topic, selected by you, and based on your solution to Exercise 26.1, suggest - for each of three process components $\Gamma_{1_0}, \Gamma_{2_0}, \Gamma_{3_0}$ - a main state, say $\Sigma_{i_0}$ (like the file systems of this chapter: FS0 was a state), and some actions, i.e., $\alpha_{i_j}$ for some $j=1,2, \ldots, n_i$ (i.e., operations and functions) on these. Sketch some state structure (Fig. 27.1 was such a sketch), and narrate some actions (etc.). (Together $\Sigma_{i_0}$ and $\left\{\alpha_{1_1}, \alpha_{1_2}, \ldots, \alpha_{1_{n_1}}\right\}$ form $\Gamma_{i_0}$.)
