Logical constant

In logic, a **logical constant** is a symbol that represents a specific logical concept or relation and has a fixed meaning across different contexts. Logical constants are fundamental to the structure of logical systems and include symbols for basic logical operations and relations. Common examples of logical constants include: 1. **Logical Connectives**: - **Negation (¬)**: Represents “not”. - **Conjunction (∧)**: Represents “and”.
