Two (partially related) research projects are planed: to work out Baym-Kadanoff equations (including renormalization) and their solution with perspectives (i) in the discussion of decoherence and entropy in non-equilibrium thermodynamics (ii) in applications in models of cosmic fluctuations generated in an inflationary period (iii) in application in models for baryogenesis. Secondly the “worldline“ method should be developed to obtain higher orders in the derivative expansion, in particular CP violating terms

计划开展两个（部分相关的）研究项目：从（i）讨论非平衡态热力学中的退相干和熵（ii）在暴胀时期产生的宇宙涨落模型中的应用（iii）在重子生成模型中的应用的角度，研究Baym-Kadanoff方程（包括重整化）及其解。其次，发展“世界线”方法以获得高阶导数展开式，特别是CP破坏项
