WebJul 6, 2024 · Definition 4.4. A pushdown automaton M is specified by six components M = (Q, Σ, Λ, q0, ∂, F) where. Q is a finite set of states. Σ is an alphabet. Σ is the input alphabet for M. Λ is an alphabet. Λ is the stack alphabet for M. q0 ∈ Q is the start state of M. F ⊆ Q is the set of final or accepting states in M. WebSo it shows that the power set of a finite set is finite. Non- Empty Finite set. It is a set where either the number of elements is big or only starting or ending is given. So, we denote it with the number of elements, n(A), and if n(A) is a natural number, then it’s a finite set. Example: S = { a set of the number of people living in India} chinese songs 80-90s
