摘要翻译：
我们研究了小世界超图上带有键无序的自旋系统的热力学性质，该超图是将一维Ising链叠加到带有p-自旋相互作用的随机Bethe图上得到的。利用转移矩阵技术，我们分别在复制对称和一步复制对称破缺近似下，导出了描述相关序参量和自由能的不动点方程。我们确定了所有温度下复制品对称性内的静态和动态铁磁相变以及spinglass相变，并证明了当考虑到复制品对称性一步破缺时对这些结果的修正。所得结果与Monte-Carlo模拟结果一致。

英文摘要：
We study the thermodynamic properties of spin systems with bond-disorder on small-world hypergraphs, obtained by superimposing a one-dimensional Ising chain onto a random Bethe graph with p-spin interactions. Using transfer-matrix techniques, we derive fixed-point equations describing the relevant order parameters and the free energy, both in the replica symmetric and one step replica symmetry breaking approximation. We determine the static and dynamic ferromagnetic transition and the spinglass transition within replica symmetry for all temperatures, and demonstrate corrections to these results when one step replica symmetry breaking is taken into account. The results obtained are in agreement with Monte-Carlo simulations.
