path integrals

Path integrals, also known as Feynman path integrals, are mathematical tools used in theoretical physics to compute the probabilities or amplitudes associated with the motion of particles or fields. They involve integrating over all possible paths a particle or field could take between an initial state and a final state, taking into account the quantum mechanical nature of the system. Path integrals provide a powerful framework for describing the behavior of quantum systems and are extensively used in quantum field theory and quantum mechanics.
