y developed covariant-evolution-operator method. This is a form of time- or energy-dependent perturbation theory, where all perturbations, including relativity and quantum electrodynamics, are built into the wave function, which is a necessary requisite for a true unification. The procedure is basedTonometry 发表于 2025-4-1 14:53:12

Gunther Dirr,Uwe Helmke,Christian Lagemand to go beyond it, not only for better accuracies but also for better understandings of relativistic quantum mechanics. It is shown here that, at variance with the usual top-down procedures for deriving relativistic Hamiltonians as approximations to quantum electrodynamics (QED), a with-pair relativ类型 发表于 2025-4-2 02:42:52
Cristian Secchi,Stefano Stramigioli,Cesare Fantuzziporated for a variety of different system structures, including series systems, mixed series-parallel systems, and general systems..Each of the problems is known as an NP-hard problem. This provided us with the motivation to develop various solution approaches, including optimal solution approaches,moratorium 发表于 2025-4-2 03:36:09
