A unary function takes a single input. It's fundamental in math and logic, seen in operations like negation and absolute…
A mathematical logic and computer science framework using types to classify expressions and objects, preventing paradoxes by organizing into hierarchies…
A 'type' categorizes entities with shared characteristics, crucial in logic and mathematics to distinguish objects and prevent paradoxes. It represents…
The turnstile symbol (⊢) signifies syntactic entailment or provability in formal logic. It indicates that a statement on the right…
The Turing thesis, also known as the Church-Turing thesis, posits that any function computable by an algorithm can be computed…
A function computable by a Turing machine, representing the theoretical limit of what can be calculated. It forms the basis…
The truth value represents whether a proposition or statement is true or false. Classical logic uses binary true/false, while many-valued…
Truth-trees, also known as analytic tableaux, are a method for testing logical validity and consistency. They systematically break down complex…
A truth table systematically displays the truth value of a compound statement for all possible truth combinations of its individual…
A truth function maps truth values (true/false) to truth values. It is fundamental in logic for defining the meaning of…
