Multi-modal logic extends classical modal logic by integrating multiple distinct types of modalities. It handles variations in necessity, possibility, knowledge,…
A monadic predicate asserts a property about a single entity within a given domain. It's a fundamental concept in logic…
A maximal consistent set is a collection of logical formulas that is both consistent and cannot be extended further without…
Explore systems beyond binary true/false. Many-valued logic incorporates additional truth values to represent uncertainty, indeterminacy, and nuanced degrees of truth…
Many-sorted logic enhances first-order logic by introducing multiple domains. Variables and quantifiers are typed, specifying the sort of objects they…
The logic of attributes extends first-order logic by incorporating attribute-value pairs. It's crucial for representing and reasoning about objects with…
Interrogative logic, also known as erotetic logic, is the formal study of questions and reasoning involving them. It explores the…
Instantiation is the core process of replacing bound variables with specific constants. This action effectively removes quantifiers, leading to concrete…
An inference rule is a logical structure that permits deriving conclusions from premises. It specifies the valid steps in reasoning,…
Inconsistency arises when a system contains contradictory elements, making it impossible for all statements to be true simultaneously. This fundamental…
