Mathematical logic is a subfield of mathematics exploring the applications of formal logic to mathematics, encompassing the study of mathematical proof, computability, and the foundations of mathematics. It provides a framework for understanding the nature of mathematical truth and the limits of mathematical reasoning, influencing areas such as set theory, model theory, and recursion theory.

Computability concerns the ability to solve a problem effectively using a finite set of operations or an algorithm. It examines which problems can be solved on a computer in principle, laying the foundation for understanding what can be achieved within computer science and logic.

computability

foundations of mathematics

Mathematical truth is an assertion or proposition that is universally accepted as correct within the framework of a given mathematical system, often derived through logical deduction and proof. It relies on axioms and established theorems, and its validity is independent of empirical observation, making it a cornerstone of mathematical rigor and consistency.

Set theory is a fundamental branch of mathematical logic that studies collections of objects, known as sets, and forms the basis for much of modern mathematics. It provides a universal language for mathematics and underpins various mathematical disciplines by defining concepts such as functions, relations, and cardinality.

set theory

Model theory is a branch of mathematical logic that studies the relationships between formal languages and their interpretations, or models. It provides tools to analyze the structure and properties of mathematical systems by examining the models that satisfy given sets of axioms or theories.

model theory

Recursion theory, also known as computability theory, is a branch of mathematical logic and computer science that studies the capabilities and limitations of algorithms in terms of what problems can be solved by them. It explores the concept of recursive functions and the classification of problems based on their solvability and computational complexity.
