## Field Theory in Mathematics

### Algebraic Structures

Algebraic structures known as fields are sets equipped with two binary operations that satisfy certain axioms

### Field Axioms

Field axioms are foundational rules that characterize the algebraic structure of a field

### Applications of Fields

Fields find applications in numerous mathematical and physical theories, such as algebra, algebraic geometry, and Galois Theory

## Field Theory in Physics

### Physical Fields

Field theory in physics is concerned with the description of physical fields, such as electromagnetic and gravitational fields, which mediate forces between objects

### Quantum Field Theory

Quantum Field Theory synthesizes principles from quantum mechanics, classical field theory, and special relativity to explain particle interactions at the quantum scale

### Gauge Field Theory

Gauge Field Theory provides a framework for understanding the fundamental forces and interactions in particle physics, based on the concept of gauge symmetries

## Advanced Field Theories

### Conformal Field Theory

Conformal Field Theory is concerned with quantum field theories that are invariant under conformal transformations and is relevant in the study of critical phenomena in statistical mechanics

### String Field Theory

String Field Theory is an extension of string theory that formulates the interactions, splitting, and joining of strings within a quantum field theoretical framework

### Effective Field Theory

Effective Field Theory is a pragmatic approach that stratifies physical systems based on their energy scales, making precise predictions in situations where a complete understanding is not feasible
