BRST Symmetry and de Rham Cohomology

Focusing on advanced concepts in quantum field theory and algebraic topology, this book delves into Hamiltonian quantization under geometrical constraints, symplectic embedding, and BRST symmetry. The new edition enhances understanding of particle phenomenology, particularly baryons and photons, through innovative models like the hypersphere soliton for baryons and stringy photon models. Additionally, it explores photon properties within the framework of Dirac-type relativistic quantum mechanics, offering a comprehensive perspective on these extended theories.
