论文摘要
分析了描述分裂相互作用的仪表理论的渐近结构。提出了两组渐近条件。两者都涵盖了所有已知的解决方案，导致有限的电荷并解决了来自单极贡献的分歧能量的问题。虽然第一组导致预期的分形式对称代数（包括偶极子电荷），但第二组为其提供了柔软的无限尺寸扩展。这些软电荷提供了类似于分形式理论的丰富红外结构的证据，并提供了可能的分裂红外三角形的一个角落。
The asymptotic structure of gauge theories describing fracton interactions is analyzed. Two sets of asymptotic conditions are proposed. Both encompass all known solutions, lead to finite charges and resolve the problem of the divergent energy coming from the monopole contribution. While the first set leads to the expected fracton symmetry algebra, including a dipole charge, the second set provides a soft infinite-dimensional extension of it. These soft charges provide evidence of a rich infrared structure for fracton-like theories and provide one corner of a possible fracton infrared triangle.
