A negative proposition asserts the absence or non-existence of something, or denies a property of an object. It's a fundamental…
Negation Normal Form (NNF) is a standard way to represent logical formulas. In NNF, negations only apply to atomic propositions,…
Negation completeness signifies a logical system's ability to prove either any given statement or its negation. This ensures that no…
Negation is a fundamental logical operation that reverses the truth value of a statement. It transforms true propositions into false…
A necessary condition is a requirement for a statement to be true. It must be met, but it doesn't guarantee…
An n-ary relation connects 'n' elements, generalizing binary relations. It's fundamental in mathematics and computer science for describing complex relationships…
Monotonicity is a property that preserves order. In logic, it means adding premises doesn't invalidate existing conclusions. In functions, it…
A monadic predicate asserts a property about a single entity within a given domain. It's a fundamental concept in logic…
Monadic first-order logic simplifies first-order logic by using only predicates with a single argument. This focuses on the properties of…
