A regular language over an alphabet ∑ is one that cannot be obtain...
An alphabet is a set of symbols or characters that are used to form words or strings in a language. A regular language is a type of formal language that can be described and recognized by a regular expression, a deterministic finite automaton (DFA), a non-deterministic finite automaton (NFA), or a regular grammar.
In the context of regular languages, an alphabet refers to the set of symbols or characters that can be used to form words in the language. For example, if we consider the alphabet {0, 1}, then a regular language over this alphabet could be the set of all binary strings that start with a 0 and end with a 1 (e.g., "0101", "0011101", etc.).
Regular languages can be defined using regular expressions, which are patterns that describe the structure of the language. For example, the regular expression "0(0+1)*1" represents the regular language mentioned earlier.
Regular languages can also be recognized by deterministic finite automata (DFA) or non-deterministic finite automata (NFA). These are abstract machines that can read input symbols and transition between states based on the current symbol and the current state. If a DFA or NFA can reach an accepting state after reading an input string, then the string belongs to the regular language.
Overall, a regular language over an alphabet refers to a set of words or strings that can be described and recognized using regular expressions, deterministic finite automata, non-deterministic finite automata, or regular grammars.
