 Topological quantum field theory

Topological Quantum Field Theory (TQFT) is a branch of theoretical physics and mathematics that explores the relationships between quantum field theory and topology, a branch of mathematics that studies properties of space that are preserved under continuous transformations. ### Key Concepts of TQFT: 1. **Quantum Field Theory (QFT)**: - QFT is a framework for constructing quantum mechanical models of subatomic particles in particle physics. It combines classical field theory, special relativity, and quantum mechanics.
