Supertask: Infinite Operations in Finite Time
A supertask involves completing an infinite sequence of operations within a finite time. This concept, often explored in philosophical paradoxes and theoretical physics, challenges our understanding of time, space, and…
Suffix Notation (Reverse Polish Notation)
Suffix notation, also known as reverse Polish notation (RPN), places operators after their operands. This efficient method is used in calculators and programming languages for simplified parsing and evaluation.
The Successor Function in Arithmetic and Logic
The successor function, denoted S(n) = n + 1, is a foundational concept in arithmetic and logic, defining the next natural number for any given number. It's crucial for building…
Subtheory: Understanding Theories Within Theories
A subtheory is a specialized theory nested within a broader one. It shares some axioms and theorems but focuses on a narrower domain, offering deeper insights into specific aspects of…
Substructural Logic
Substructural logics are non-classical systems that alter or remove structural rules of classical logic, like relevance and linear logic, impacting resource sensitivity and proof structure.
Substitutional Quantifier
A substitutional quantifier ranges over expressions or names, not objects. It's crucial in theories of reference and meaning, offering a unique perspective on quantification in language and logic.
Substitution Instance in Logic
A substitution instance is the result of replacing variables in a well-formed formula with other formulas. Each variable must be consistently replaced wherever it appears.
Substitution in Logic
Substitution is the fundamental act of replacing variables or expressions in logical formulas with others. It's crucial for maintaining logical consistency and enabling logical reasoning and proof construction.
Subordinate Connective in Logic
A subordinate connective is a logical operator appearing within the scope of another logical operator in a compound proposition. It is essential for understanding complex logical structures and evaluating truth…
Sublogic: Understanding Subset Logical Systems
A sublogic is a logical system that forms a subset of a more extensive logic. It preserves certain operations and principles from the parent system while omitting others, creating a…
