The project aims at an identification of and a possible discrimination between recently developed scenarios for confinement based on standard pseudoparticle solutions (merons, instantons or Harrington-Shepard calorons) on the one hand and calorons with non-trivial holonomy on the other. We shall concentrate on zero-temperature and on nonzero-temperature confining as well as deconfining field ensembles in SU(N) Yang-Mills theory and/or full QCD. Special emphasis will be layed on the rôle of meron solutions, which have so far received much less attention than the other pseudoparticles. Systematic model computations within these scenarios will be confronted with lattice field theory investigations including various recently developed filtering techniques as there are smearing and mode expansions of the lattice Dirac as well as of the Laplacian operator.

该项目的目的是确定和区分最近开发的基于标准伪粒子解决方案（merons，instantons或Harrington-Shepard calorons）的限制方案和具有非平凡完整性的calorons。我们将集中讨论SU（N）Yang-Mills理论和（或）全QCD中的零温度场系综、非零温度场系综以及解限制场系综。特别强调的是meron解决方案的作用，迄今为止得到的关注比其他赝粒子少得多。在这些情况下，系统的模型计算将面临格场理论的调查，包括各种最近开发的过滤技术，因为有涂抹和模式扩展的晶格狄拉克以及拉普拉斯算子。
