existential quantification

Existential quantification is a way of expressing that something exists with certain properties. In logic, it’s written as “∃,” meaning “there exists at least one” element for which a statement is true. For example, “∃x, x is a dog” means “There is at least one thing called x that is a dog.” It focuses on confirming the existence of at least one example without specifying which one or how many. This concept helps us formalize statements about the existence of objects or conditions within a logical framework.
