可以选择额外维区间上的边界条件来打破体规范对称性并降低规范群的秩。我们考虑这种机制的模型与规范三位一体化。我们确定的边界条件所需的打破三化规范组直接下降到标准模型。工作在一个有效的理论规范对称性破缺参数的边界上，我们研究的限制，其中大统一理论破缺扇区是希格斯，并显示如何可以获得最小超对称标准模型的低能粒子含量。我们发现，规范统一是保存在这种情况下，和微分规范耦合运行是对数以上的规模紧化。我们比较我们的模型的现象学的四维“三化”理论。
Boundary conditions on an extra dimensional interval can be chosen to break bulk gauge symmetries and to reduce the rank of the gauge group. We consider this mechanism in models with gauge trinification. We determine the boundary conditions necessary to break the trinified gauge group directly down to that of the standard model. Working in an effective theory for the gauge-symmetry-breaking parameters on a boundary, we examine the limit in which the grand-unified theory-breaking-sector is Higgsless and show how one may obtain the low-energy particle content of the minimal supersymmetric standard model. We find that gauge unification is preserved in this scenario, and that the differential gauge coupling running is logarithmic above the scale of compactification. We compare the phenomenology of our model to that of four dimensional 'trinified' theories.
