Path integral differential equation
WebJan 1, 1981 · This chapter focuses on path integrals and partial differential equations. It considers an equation of the form du/dt = Au, where u belongs to a Banach space B, … WebAccording to Feynman, this amplitude is equivalently given by the path integral I= Z [dq]eiS[q]=„h which is a integral over all functions (or paths)q(t) which satisfyq(ti) =qi, q(tf) =qf. Obviously this needs to be better deflned, but we will try to make sense of it as we go along. QFT15 t2t1
