Behavioural Physiology of Farm Mammals,We extend the perturbation theory of the previous chapter by going one order further and permitting several degrees of freedom. So let the unperturbed problem ..(..) be solved. Then we expand the perturbed Hamiltonian in the (.., ..)-“basis” according toFACT 发表于 2025-3-27 03:18:25
https://doi.org/10.1007/978-3-642-85278-7In the present chapter we are concerned with systems, the change of which — with the exception of a single degree of freedom — should proceed slowly. (Compare the pertinent remarks about ε as slow parameter in Chap. 7.) Accordingly, the Hamiltonian reads:reserve 发表于 2025-3-27 07:51:10

Introduction,The subject of this monograph is classical and quantum dynamics. We are fully aware that this combination is somewhat unusual, for history has taught us convincingly that these two subjects are founded on totally different concepts; a smooth transition between them has so far never been made and probably never will.Coronary 发表于 2025-3-28 01:28:47
